Question:

Select the set in which the numbers are related in the same way as are the numbers of the following set.

(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/subtracting /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)

(23, 308, 15)

(18, 187, 12)

Options:

(14, 104, 9)

(19, 325, 27)

(20, 280, 14)

(16, 122, 7)

Correct Answer:

(14, 104, 9)

Explanation:

(23, 308, 15)

(18, 187, 12)

The logic followed here is :

(Ist number ×  IIIrd number) - ( Ist number IIIrd number) + 1 = second number

As

(23 × 15) - ( 23 +15 ) + 1 = 308

(18 × 12) - ( 18 +12 ) + 1 = 187

same as in (14, 104, 9)

(14 × 9) - ( 14 +9 ) + 1 = 104
