Question:

Select the option in which the numbers shares the same relationship in set as that shared by the numbers in the given 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)

 (14, 112, 6)

(17, 204, 5)

Options:

(21, 189, 12)

(24, 145, 18)

(9, 89, 3) 

(15, 135, 7)

Correct Answer:

(21, 189, 12)

Explanation:

 (14, 112, 6)

(17, 204, 5)

The logic followed here is :

(Ist number)2 (Ist number × IIIrd number) = second number

as

(14 )2 -  (14 )× 6 = 112

(17)2 -  (17) × 6 = 204

same as (21, 189, 12)

(21)2 (21) × 12 = 189
