GATE General Aptitude & Logical Reasoning 1

Question 1

What is the next number in the sequence: 2, 4, 8, 16, __?

Accepted Answer

32

Answer

The sequence 2, 4, 8, 16 follows a pattern where each number is obtained by multiplying the previous number by 2. This is a geometric progression with a common ratio of 2. Therefore, to find the next number, you multiply the last number (16) by 2, which gives 32.

Question 2

If A = 2, B = 4, C = 6, D = 8, then E = ?

Accepted Answer

10

Answer

The pattern assigns a value to each letter that is twice its alphabetical position. A is the 1st letter, so A=1*2=2. B is the 2nd letter, so B=2*2=4. C is the 3rd letter, so C=3*2=6. D is the 4th letter, so D=4*2=8. Following this pattern, E is the 5th letter, so E=5*2=10.

Question 3

A train travels 60 miles in 1.5 hours. What is its average speed?

Accepted Answer

40 mph

Answer

To find the average speed, you divide the total distance traveled by the total time taken. In this case, the train travels 60 miles in 1.5 hours. Therefore, the average speed is calculated as 60 miles / 1.5 hours = 40 miles per hour (mph).

Question 4

If 5 pens cost $10, how much do 8 pens cost?

Accepted Answer

$16

Answer

First, determine the cost per pen: $10 divided by 5 pens equals $2 per pen. Then, to find the cost of 8 pens, multiply the cost per pen by 8. So, $2/pen * 8 pens = $16. Therefore, 8 pens would cost $16.

Question 5

Find the odd one out: Apple, Banana, Carrot, Mango.

Accepted Answer

Carrot

Answer

Apple, Banana, and Mango are all types of fruits. Carrot, however, is a root vegetable. Therefore, 'Carrot' is the odd one out because it belongs to a different botanical category than the other items in the list.
