(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.
