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)

(17, 59, 625)

(8, 44, 784)

Options:

(22, 78, 784)

(12, 69, 2025)

(24, 70, 576)

(18, 74, 1296)

Correct Answer:

(12, 69, 2025)

Explanation:

(17, 59, 625)

(8, 44, 784)

The logic followed here is :

IInd number - ( ist number× 2 ) = Square root of iiird number

As

59 - (17 × 2 ) = Square root of 625

59 - 34 = 25

25 = 25

and

44 - (8 × 2 ) = Square root of 784

44  - 16 = 784

28 = 28

Similarly (12, 69, 2025)

69 - (12 × 2 ) = Square root of 2025

69 - 24 = 45

45 = 45
