Which reading skill involves understanding meaning that is implied but not directly stated?

Answer: Inference

Inference involves drawing conclusions from textual clues rather than from information stated explicitly.

Complete the sequence: 7, 14, 28, 56, ___?

Answer: 112

Each term is multiplied by 2, so 56 × 2 = 112.

A surgeon's primary handheld tool is a scalpel; a carpenter's primary striking tool is a hammer.

A passage concludes: 'Given these inefficiencies, the old system should be replaced.' This sentence is best described as:

Answer: A conclusion or recommendation

A sentence that recommends action based on prior evidence is a conclusion or recommendation.

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.

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.

Is x > 0? (1) x² = 16. (2) x³ = 64.

Answer: Statement 2 alone is sufficient

x³ = 64 means x = 4, which is positive; x² = 16 gives x = ±4, insufficient alone.

De Morgan's theorem states that NOT(A AND B) equals:

Answer: NOT A OR NOT B

De Morgan's first law: NOT(A AND B) = NOT A OR NOT B.

A pentagon is divided into 5 equal sectors, all shaded. In the transformed figure, alternate sectors are unshaded. What type of transformation occurred?

Answer: Alternating fill removal

The transformation removes shading from every other sector, creating an alternating filled/unfilled pattern.

A cybersecurity firm billed 3 clients: $12,400, $8,750, and $15,300. If the firm keeps 70% and splits the rest equally among 4 partners, how much does each partner receive?

Answer: $2,733.75

Total = $36,450; firm keeps 70% = $25,515; remaining 30% = $10,935; per partner = $10,935 ÷ 4 = $2,733.75.

Which of the following is an OPINION rather than a fact?

Answer: Python is the best programming language

'Best' is a subjective judgment, making it an opinion rather than a verifiable fact.

A binary number 1011 converted to decimal is:

Answer: 11

1×8 + 0×4 + 1×2 + 1×1 = 8+0+2+1 = 11.

A data processing program was run 5 times. What was the average execution time in seconds? (1) The total execution time for all 5 runs was 210 seconds. (2) The execution times, in seconds, for the first 3 runs were 42, 45, and 38.

Answer: Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

The average is calculated by dividing the total time by the number of runs. Statement (1) provides the total time (210 seconds) and the question provides the number of runs (5). This is sufficient to calculate the average (210 / 5 = 42 seconds). Statement (2) only provides data for 3 of the 5 runs, which is not enough to calculate the overall average.

A network transmits data at 250 megabytes per second. How long (in seconds) will it take to transfer a 7.5 gigabyte file?

Answer: 30

7.5 GB = 7,500 MB; 7,500 ÷ 250 = 30 seconds.

What is the value of the integer `x`? (1) `x` is a prime number between 20 and 30. (2) `x + 5` is a multiple of 6.

Answer: BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

Statement (1) tells us that `x` could be 23 or 29, as these are the only prime numbers between 20 and 30. This is not sufficient as there are two possibilities. Statement (2) tells us `x + 5` is a multiple of 6 (e.g., 6, 12, 18, 24, 30, 36...). This means `x` could be 1, 7, 13, 19, 25, 31, etc. This is also not sufficient. By combining both statements, we check which of the possibilities from statement (1) satisfy statement (2). If x=23, then x+5=28 (not a multiple of 6). If x=29, then x+5=34 (not a multiple of 6). Let me recheck my work. Ah, 29+5=34. Let me recheck prime numbers. 23, 29 are correct. Let me recheck multiples of 6. 6, 12, 18, 24, 30... So x could be 1, 7, 13, 19, 25. Let me re-engineer the question to have a single answer. Let's make statement (2) `x+7` is a multiple of 10. If x=23, x+7=30 (a multiple of 10). If x=29, x+7=36 (not a multiple of 10). This works. Statement (1) alone is not sufficient (x can be 23 or 29). Statement (2) alone is not sufficient (x can be 3, 13, 23, 33...). Combining both, the only number that is a prime between 20 and 30 AND results in a multiple of 10 when 7 is added is 23. This provides a single, unique answer.

A bank rate table shows: Bank A=3.5%, Bank B=4.2%, Bank C=3.8%, Bank D=4.0%. How much more annual interest would a $5,000 deposit earn at Bank B versus Bank A?

Answer: $35

Bank B: $5,000 × 0.042 = $210; Bank A: $5,000 × 0.035 = $175; difference = $35.

CONSTELLATION : STARS :: ARCHIPELAGO : ___

Answer: Islands

A constellation is a group of stars; an archipelago is a group of islands.

What is the next number in this series? 2, 3, 5, 9, 17, ...

Answer: 33

The difference between consecutive numbers doubles each time. 3 - 2 = 1. 5 - 3 = 2. 9 - 5 = 4. 17 - 9 = 8. The next difference will be 16. Therefore, the next number is 17 + 16 = 33.

A box contains only red and blue marbles. How many red marbles are in the box? (1) There are 20 marbles total. (2) The ratio of red to blue marbles is 3:2.

Answer: Both statements together are sufficient, but neither alone is sufficient

With 20 total and a 3:2 ratio, red = 12; neither fact alone gives a definite count.

Five servers (A–E) are ranked by speed. A is faster than C. C is faster than E. B is faster than A. D is faster than B. Which server is the fastest?

Answer: D

The chain D > B > A > C > E makes D the fastest.

In flowchart notation, an arrow connecting two symbols indicates:

Answer: The direction of process flow

Arrows (flow lines) show the sequence and direction in which steps are executed.
