31 is related to 152 by certain logic. Following the same logic, 47 is related to 168. To which of the following is 66 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.)

Show answer & explanation

Correct answer: D

Analyze the first pair (31 to 152):

31 * 5 = 155

155 - 3 = 152

Analyze the second pair (47 to 168):

If we use the same pattern: 47 * 5 = 235; 235 - 3 = 232. This does not equal 168.

Let's look for another relationship:

152 - 31 = 121

168 - 47 = 121

This reveals a constant difference pattern: (Number + 121) = Result.

Apply to the target number (66):

66 + 121 = 187.
