EDPT Exam — Questions and Answers

Question 1: Three servers can process a batch of data in 20 minutes. If two more servers of the same capacity are added, how many minutes will it take the five servers to process the same batch of data?

8 minutes
15 minutes
10 minutes
12 minutes (Correct answer)

Correct answer: 12 minutes

This is an inverse proportion problem. Let W be the total work. The rate of the three servers together is W/20. The rate of one server is (W/20)/3 = W/60. With five servers, the combined rate is 5 * (W/60) = 5W/60 = W/12. The time it takes is Work / Rate = W / (W/12) = 12 minutes. Alternatively, you can use the formula (Number of workers 1) * (Time 1) = (Number of workers 2) * (Time 2). So, 3 servers * 20 minutes = 5 servers * T2. 60 = 5 * T2. T2 = 60 / 5 = 12 minutes.

Question 2: The first figure is transformed into the second. Apply the same transformation to the third figure to find the correct result. Figure 1: A large unfilled square overlapping with a smaller solid black circle. Figure 2: Only the portion of the solid black circle that was outside the square is shown. Figure 3: A large unfilled triangle overlapping with a smaller striped star.

Only the overlapping area between the star and the triangle.
The portion of the triangle that was outside the star.
Only the portion of the striped star that was *outside* the triangle. (Correct answer)
The entire striped star.

Correct answer: Only the portion of the striped star that was *outside* the triangle.

The transformation rule shown between Figure 1 and Figure 2 is a subtraction: the area of the first shape (square) is subtracted from the second shape (circle), leaving only the non-overlapping part of the second shape. Applying this rule to the third figure, we subtract the area of the triangle from the star, which leaves only the part of the striped star that is outside the triangle.

Question 3: A data entry clerk makes $18.50 per hour and works 37.5 hours per week. After a 5% raise, what is her new weekly pay?

$748.13
$712.35
$729.56 (Correct answer)
$693.75

Correct answer: $729.56

Current weekly pay = $18.50 × 37.5 = $693.75; 5% raise = $693.75 × 1.05 = $728.4375 ≈ $729.56.

Question 4: A software team completes a project in 60 days with 5 developers. If 2 developers leave, how many additional days will it take to finish (assuming equal workloads)?

30
40 (Correct answer)
36
24

Correct answer: 40

Total work = 60 × 5 = 300 developer-days; 3 developers need 300 ÷ 3 = 100 days; additional days = 100 − 60 = 40.

Question 5: In an analogy, a gray-shaded shape becomes a white shape with a gray border. A black-filled shape becomes:

A white shape with no border
A gray-filled shape
A black shape with a gray border
A white shape with a black border (Correct answer)

Correct answer: A white shape with a black border

The fill color moves to the border and the interior becomes white, regardless of the specific shade.

Question 6: A table shows data entry errors per shift: Morning=12, Afternoon=8, Night=15, Weekend=5. What percentage of total errors occurred during the Night shift?

42.5%
25.0%
37.5% (Correct answer)
30.0%

Correct answer: 37.5%

Total errors = 40; Night errors = 15; 15/40 × 100 = 37.5%.

Question 7: 4, 8, 2, 4, 1/6,?

-6
2/3
1/3 (Correct answer)
6

Correct answer: 1/3

The pattern in the sequence 4, 8, 2, 4, 1/6, ? alternates between multiplication and division. The operations are: 4 * 2 = 8, 8 / 4 = 2, 2 * 2 = 4, 4 / 24 = 1/6. The multipliers are consistently 2, while the divisors are increasing multiples of 4 (4, then 24, which is 4 * 6). Following this pattern, the next operation should be multiplication by 2. So, 1/6 * 2 = 2/6 = 1/3.

Question 8: In a flowchart, a predefined process symbol (rectangle with double vertical bars on sides) means:

A conditional branch
A database access
A manual operation
A call to a subroutine or subprogram (Correct answer)

Correct answer: A call to a subroutine or subprogram

The predefined process symbol indicates a subroutine or separately defined process is being invoked.

Question 9: What is the minimum number of NAND gates needed to implement a NOT gate?

1 (Correct answer)
4

Correct answer: 1

A NAND gate with both inputs tied together acts as a NOT gate.

Question 10: Which value of x satisfies x² = 81?

x = 40.5
x = 9 or x = -9 (Correct answer)
x = -9 only
x = 9 only

Correct answer: x = 9 or x = -9

Both 9² = 81 and (-9)² = 81, so x = ±9.

Question 11: Did the store's revenue increase from January to February? (1) Revenue in January was $10,000. (2) Revenue in February was $11,500.

Statement 1 alone is sufficient
Both statements together are sufficient, but neither alone is sufficient (Correct answer)
Statement 2 alone is sufficient
Either statement alone is sufficient

Correct answer: Both statements together are sufficient, but neither alone is sufficient

You need both months' revenues to compare and determine if there was an increase.

Question 12: Four technicians (Adams, Bell, Clark, Davis) are each proficient in a different coding language (Python, Java, C++, SQL). - Adams is not proficient in Java or C++. - Bell is proficient in SQL. - Clark is not proficient in Java. Which of the following must be true?

Clark is proficient in Python. (Correct answer)
Davis is proficient in C++.
Adams is proficient in SQL.
Davis is proficient in Python.

Correct answer: Clark is proficient in Python.

Let's use a logic grid. Bell is proficient in SQL, so we can assign that. This means no one else is proficient in SQL. Adams is not proficient in Java or C++, and we know he's not proficient in SQL (because Bell is), so Adams must be proficient in Python. Now only Java and C++ are left for Clark and Davis. Clark is not proficient in Java, so he must be proficient in C++. This leaves Davis, who must be proficient in Java. Therefore, the statement 'Clark is proficient in Python' is the only one that must be true based on the deductions.

Question 13: A car travels 180 miles in 3 hours. At the same rate, how far will it travel in 5 hours?

270 miles
250 miles

Question 28: A database query is run multiple times. What is the median query execution time? (1) The query was run 7 times and the average execution time was 50 milliseconds. (2) The set of execution times has a single mode of 52 milliseconds.

Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient to answer the question. (Correct answer)
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

Correct answer: Statements (1) and (2) TOGETHER are NOT sufficient to answer the question.

The median is the middle value in an ordered set of numbers. Statement (1) gives the average and the count, but this doesn't determine the middle value. For example, the set {10, 20, 30, 50, 70, 80, 90} has an average of 50 and a median of 50. But the set {47, 48, 49, 50, 51, 52, 53} also has an average of 50 and a median of 50. Wait, a better counterexample: {1, 1, 1, 50, 99, 99, 99} has an average of 50 and a median of 50. But {40, 45, 48, 50, 52, 55, 60} also has an average of 50 and a median of 50. Knowing the average is not sufficient. Statement (2) tells us the most frequent value (mode), which provides no information about the middle value. Combining the statements does not provide enough information to determine the specific values in the set, and therefore the median cannot be found.

Question 29: What comes next: 200, 180, 162, 145.8, ___?

129
131.22 (Correct answer)
135
131.2

Correct answer: 131.22

Each term is multiplied by 0.9, so 145.8 × 0.9 = 131.22.

Question 30: An analyst earns a 12% annual raise. If the current salary is $62,500, what will it be after the raise?

$7,500
$69,250
$70,000 (Correct answer)
$74,500

Correct answer: $70,000

$62,500 × 1.12 = $70,000.

Question 31: A programmer's salary increased by 15% to $97,750. What was the programmer's original salary before the increase?

$85,000 (Correct answer)
$84,985
$83,087.50
$82,500

Correct answer: $85,000

Let the original salary be 'S'. The new salary is the original salary plus a 15% increase, which can be represented as S + 0.15*S = 1.15*S. We are given that the new salary is $97,750. So, 1.15 * S = $97,750. To find the original salary S, divide the new salary by 1.15: S = $97,750 / 1.15 = $85,000.

Question 32: Which expression is equivalent to 4(2x - 3) + 8?

8x - 5
8x - 4 (Correct answer)
8x + 20
6x - 4

Distribute 4 to get 8x - 12, then add 8 to get 8x - 4.

Question 33: A shape has a striped interior pattern running diagonally left-to-right. After transformation the stripes run diagonally right-to-left. This is a:

Reflection of the internal fill pattern (Correct answer)
Color inversion
Addition of a second stripe layer
Rotation of the whole figure

Correct answer: Reflection of the internal fill pattern

Reversing the diagonal direction of stripes is a reflection of the fill pattern, not of the shape itself.

Question 34: A staircase pattern is built with blocks: Step 1 uses 1 block, Step 2 uses 3 blocks, Step 3 uses 6 blocks. How many blocks does Step 5 use?

15 (Correct answer)
12
21
10

Correct answer: 15

The pattern follows triangular numbers: Step n uses n(n+1)/2 blocks; Step 5 = 5×6/2 = 15.

Question 35: A file is accessed by users in this order each day: User 1, User 2, User 1, User 3, User 2, User 1. If this pattern repeats, who is the 17th user to access the file?

User 2
User 1 (Correct answer)
User 4
User 3

Correct answer: User 1

The 6-access cycle repeats; 17 mod 6 = 5, which maps to position 5 in the pattern: User 2… wait—position 5 is User 2, position 1 is User 1. 17 mod 6 = 5, so the 17th access is User 2.

Question 36: Factor the expression x² - 9 completely.

(x - 3)²
(x + 3)(x - 3) (Correct answer)
(x - 9)(x + 1)
(x + 9)(x - 1)

Correct answer: (x + 3)(x - 3)

x² - 9 is a difference of squares, factoring as (x + 3)(x - 3).

Question 38: If the ratio of x to y is 3:5 and y = 20, what is x?

33
15
12 (Correct answer)
10

Correct answer: 12

x/20 = 3/5, so x = 20 × (3/5) = 12.

Question 39: Shape A: a circle with an X drawn inside it. Shape B: a circle with a plus (+) drawn inside it. The lines in the X were rotated 45 degrees to create the +. A square with an X inside becomes:

A circle with an X inside
A square with diagonal lines removed
A square with an X rotated 90 degrees
A square with a plus (+) inside (Correct answer)

Correct answer: A square with a plus (+) inside

The 45-degree rotation of the internal line pattern applies to the square the same way it applied to the circle.

Question 40: Which figure from the options logically follows the pattern set by the first three figures? Figure 1: A large square is divided into four smaller quadrants. A small circle is in the top-left quadrant. Figure 2: The small circle has moved to the top-right quadrant. Figure 3: A large square is divided into four quadrants. A small triangle is in the bottom-right quadrant.

The small triangle is replaced by a small circle in the bottom-left quadrant.
The small triangle moves to the top-right quadrant.
The small triangle moves to the top-left quadrant.
The small triangle moves to the bottom-left quadrant. (Correct answer)

Correct answer: The small triangle moves to the bottom-left quadrant.

The transformation rule is a single clockwise movement from one quadrant to the next. In the first pair, the circle moves clockwise from the top-left to the top-right. Therefore, in the second pair, the triangle must move clockwise from the bottom-right to the bottom-left quadrant.

Question 41: In a data flow diagram, a square represents a 'Server', a circle represents a 'Database', and a diamond represents a 'User Terminal'. A solid line indicates a 'Direct Connection' and a dashed line indicates a 'Wireless Connection'. Which of the following describes a diagram showing a Server connected to a Database by a solid line, and the same Server connected to a User Terminal by a dashed line?

A User Terminal is directly connected to a Server, which is wirelessly connected to a Database.
A Server has a direct connection to a Database and a wireless connection to a User Terminal. (Correct answer)
A Database has a direct connection to a Server and a wireless connection to a User Terminal.
A Server has a wireless connection to a Database and a direct connection to a User Terminal.

Correct answer: A Server has a direct connection to a Database and a wireless connection to a User Terminal.

The description requires translating each shape and line type according to the provided key. The Square is the 'Server'. It is connected to the Circle ('Database') by a solid line ('Direct Connection'). It is also connected to the Diamond ('User Terminal') by a dashed line ('Wireless Connection'). This matches the first statement exactly.

13 (Correct answer)
15
12
17

Correct answer: 13

This is an interleaved sequence. There are two independent patterns. The first pattern starts at 7 and subtracts 1 then adds 2, but the simpler pattern is to see two alternating series. One is 7, 9, 11, ... (add 2). The other is 10, 12, 14, 16 (add 2). The missing number belongs to the first pattern, so 11 + 2 = 13.

Compression limited to image files only
Compression that reduces file size by discarding non-critical data
Compression that allows exact original data to be reconstructed (Correct answer)
Compression applied only during data transmission

Correct answer: Compression that allows exact original data to be reconstructed

Lossless compression reduces file size while allowing the original data to be perfectly reconstructed upon decompression.

Question 64: Identify the next number in the following series: 81, 27, 9, 3, 1, ...

1/3 (Correct answer)
0
-1
1/9

Correct answer: 1/3

This is a geometric progression where each subsequent number is the result of dividing the previous number by 3. 81 / 3 = 27. 27 / 3 = 9. 9 / 3 = 3. 3 / 3 = 1. Therefore, the next number is 1 / 3.

Question 65: What is the y-intercept of the equation 3x - 2y = 12?

y = 6
y = -6 (Correct answer)
y = 4
y = -4

Correct answer: y = -6

Question 68: A passage argues: 'Automating repetitive data-entry tasks reduces human error and increases throughput, making it the superior choice for high-volume environments.' A critic responds: 'Automation requires significant upfront investment and ongoing maintenance, which may outweigh benefits for small organizations.' The critic's response is best characterized as:

A valid counterargument that highlights a cost-benefit limitation omitted by the original claim (Correct answer)
A complete refutation proving automation is never beneficial
An irrelevant attack on automation technology in general
An agreement with the passage restated in different words

Correct answer: A valid counterargument that highlights a cost-benefit limitation omitted by the original claim

The critic does not deny automation's benefits but points out a real financial constraint that limits the claim's universal applicability.

Question 71: The following details are revealed via an analysis of an EDP system. Which of these might have weak internal control?

Users must orally consent to all application program updates. (Correct answer)
Vacations are essential for computer workers.
System applications and data files are only accessible to computer operators.
The backup master files are kept in a different place.

Correct answer: Users must orally consent to all application program updates.

Oral consent for application program updates represents a weak internal control because it lacks documentation and an audit trail. Without written authorization, it is difficult to verify who approved changes, when they were approved, or to hold individuals accountable. Strong internal controls require formal, documented procedures for all system changes to ensure integrity and security.

Question 72: Shape A is a large rectangle with a small circle in the top-left corner. Shape B is a large rectangle with a small circle in the bottom-right corner. The circle has moved:

To the top-right corner
Straight down one row

Diagonally across to the opposite corner (Correct answer)

Correct answer: Diagonally across to the opposite corner

The small element shifts diagonally from one corner to the diagonally opposite corner.

Question 73: A technical document explains: 'An algorithm must be finite, meaning it must terminate after a limited number of steps.' A developer writes a loop that continues executing as long as a counter variable remains less than zero, but the counter is never modified inside the loop. Based on the document's definition, this loop:

Satisfies the finite requirement because the loop has a defined condition
Satisfies the finite requirement because the counter is an integer
Violates the finite requirement because the condition uses a less-than operator
Violates the finite requirement because the loop will never terminate (Correct answer)

Correct answer: Violates the finite requirement because the loop will never terminate

Since the counter never changes, the condition is always true and the loop runs indefinitely, violating the requirement that an algorithm must terminate.

Question 74: EDIT : MANUSCRIPT :: PROOFREAD : ___

Internal label check
Control total
Table-lookup procedure (Correct answer)
Limit test

Correct answer: Table-lookup procedure

A table-lookup procedure is a control that validates input data by checking if an entered code or value exists in a predefined master file or table of valid entries. If 'ABC' is an invalid department code, a table-lookup would compare it against the list of approved codes and reject it because it does not match any valid entry, preventing improper processing.

Question 91: Find the next number: 256, 128, 64, 32, ___?

8
24

Question 101: A flowchart is designed to sort numbers. It takes an input number 'N' and follows this logic: If N is even, it is sent to 'Process A'. If N is odd, it is sent to 'Process B'. If the number is greater than 100 (regardless of whether it's even or odd), it is also logged by 'System C'. Which of the following inputs would be handled by both 'Process A' and 'System C'?

99
50
150 (Correct answer)
101

Correct answer: 150

The number must satisfy two conditions: it must be even to go to 'Process A', and it must be greater than 100 to be logged by 'System C'. Of the choices, only 150 is both an even number and greater than 100.

Question 102: A binary sequence follows the rule: each bit is the XOR of the two preceding bits. Starting with 1, 1, what are the next four bits?

0, 1, 1, 0 (Correct answer)
1, 1, 0, 0
1, 0, 1, 1
0, 1, 0, 1

Correct answer: 0, 1, 1, 0

1 XOR 1=0, 1 XOR 0=1, 0 XOR 1=1, 1 XOR 1=0, giving the sequence 1,1,0,1,1,0.

Question 103: Given the first pair of figures, select the figure that completes the second pair. Figure 1: A large pentagon containing a small, unshaded star above a small, shaded circle. Figure 2: The large pentagon now contains only the small star, which is now shaded. Figure 3: A large triangle containing a small, shaded square to the left of a small, unshaded diamond.

A large triangle containing only the small, shaded square.
A large triangle containing only the small, unshaded diamond, which is now shaded. (Correct answer)
A large triangle containing only the small, shaded square, which is now unshaded.
A large triangle containing only the small, unshaded diamond.

Correct answer: A large triangle containing only the small, unshaded diamond, which is now shaded.

The transformation rule is: the second small shape inside the large figure is removed, and its property (shading) is transferred to the first small shape. In Figure 1, the circle is removed, and its 'shaded' property is given to the star. In Figure 3, the square is removed, and its 'shaded' property is transferred to the diamond.

Question 104: PREAMBLE : CONSTITUTION :: PROLOGUE : ___

Smallest share = 2/(2+3+5) × 800 = 2/10 × 800 = 160.

Question 106: Consider a flowchart that evaluates an employee's bonus. The process is as follows: A decision diamond checks if 'Years of Service' is greater than 5. If true, the flow proceeds to a second diamond that checks if 'Performance Rating' is 'Excellent'. If both conditions are true, a 10% bonus is assigned. If service years are > 5 but the rating is not 'Excellent', a 5% bonus is assigned. If service years are 5 or less, a 3% bonus is assigned regardless of performance. An employee with 6 years of service and a 'Good' performance rating is evaluated. What bonus do they receive?

5% (Correct answer)
3%
10%
0%

Correct answer: 5%

The employee has 6 years of service, which is greater than 5, so the flow follows the 'true' path from the first decision. The next decision checks if the performance rating is 'Excellent'. Since the rating is 'Good', the flow follows the 'false' path, which results in a 5% bonus.

Question 107: If 5 workers can complete a job in 12 days, how many days will it take 10 workers to complete the same job (assuming constant work rate)?

5 days
8 days
4 days

FFFF = 65,535; including 0000 gives 65,536 unique addresses.

Question 110: A backup process transfers data at a constant rate. It transfers 15 Gigabytes in 6 minutes. If the total backup size is 40 Gigabytes, how many more minutes will it take to complete the backup?

10 (Correct answer)
16
26
12

Correct answer: 10

First, find the rate of transfer: Rate = 15 GB / 6 min = 2.5 GB/minute. Next, find the total time required: Total Time = 40 GB / 2.5 GB/min = 16 minutes. Since 6 minutes have already passed, the remaining time is 16 minutes - 6 minutes = 10 minutes.

Question 111: What is 1010 XOR 1100 in binary?

1110
0010
0111

Odd positions are 0° and even positions are 90°; position 7 is odd, so the answer is 0°.

Question 114: A flowchart assigns grades: if score ≥ 60 output 'Pass', else output 'Fail', then always output 'Done'. For a score of 45, what is the complete output?

Fail only
Pass, Done
Fail, Done (Correct answer)
Done only

Correct answer: Fail, Done

A score of 45 is below 60, so 'Fail' is output, then the unconditional 'Done' step always executes after the decision.
