CLAT Logical Reasoning & Quantitative Techniques

Question 1

What comes next in the series: 2, 4, 8, 16, __?

Accepted Answer

32

Answer

This is a simple geometric progression where each number is obtained by multiplying the previous number by 2. Following the pattern: 2 * 2 = 4, 4 * 2 = 8, 8 * 2 = 16. Therefore, the next number in the series is 16 * 2 = 32.

Question 2

Which number is the odd one out: 3, 5, 7, 9, 11?

Accepted Answer

9

Answer

In the given series (3, 5, 7, 9, 11), all numbers except 9 are prime numbers. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The number 9 is a composite number because it can be divided by 3 (in addition to 1 and 9).

Question 3

Find the missing number: 6, 11, 21, 36, __

Accepted Answer

56

Answer

Let's find the difference between consecutive numbers: 11 - 6 = 5, 21 - 11 = 10, 36 - 21 = 15. The differences are increasing by 5 each time (5, 10, 15). Therefore, the next difference should be 20. Adding 20 to the last number (36) gives 36 + 20 = 56.

Question 4

Which is a valid conclusion: All lawyers are professionals. John is a lawyer.

Accepted Answer

John is a professional

Answer

This is a classic example of a deductive syllogism. The first premise states that "All lawyers are professionals." The second premise states that "John is a lawyer." Based on these two premises, it logically follows that John must also be a professional, as he belongs to the category of lawyers.

Question 5

If A = 1, B = 2, ..., what is the value of 'CAB'?

Accepted Answer

7

Answer

The numerical value of each letter is its position in the alphabet (A=1, B=2, C=3). The pattern to determine the value of 'CAB' is to multiply the value of the first letter (C) by the value of the last letter (B), and then add the value of the middle letter (A). Thus, (3 * 2) + 1 = 6 + 1 = 7.
