10 is related to 15 following certain logic. Following the same logic, 42 is related to 63. To which of the following numbers is 22 related, following the same logic?
(NOTE : Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /multiplying etc., to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

- B.
30
- C.
33

Show answer & explanation
Correct answer: C
The relationship between the numbers is based on a consistent multiplication factor. In the first pair, 10 is related to 15 because multiplying 10 by 1.5 yields 15 (10 × 1.5 = 15). This same logic applies to the second pair: multiplying 42 by 1.5 results in 63 (42 × 1.5 = 63). To find the number related to 22, we apply this identical multiplier. Multiplying 22 by 1.5 gives 33 (22 × 1.5 = 33). Therefore, the correct answer is 33.\nOption A (28) and Option B (30) are incorrect because they do not result from multiplying 22 by the established factor of 1.5. Option D (31) is also incorrect as it does not fit the pattern. The consistent logic across all pairs confirms that 33 is the only valid answer.
