Question : Directions: In the following number pairs, the second number is obtained by applying certain mathematical operations to the first number. Select the set in which the numbers are related in the same way as the numbers of the following sets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(17, 280)
(22, 475)

Option 1: (21, 450)

Option 2: (26, 485)

Correct Answer: (13, 160)


Solution : Given:
(17, 280); (22, 475)

Here, (17, 280)→(17) 2 – 9 = 289 – 9 = 280
(22, 475)→(22) 2 – 9 = 484 – 9 = 475

Let's check the options –
First option: (21, 450)→(21) 2 – 9 = 441 – 9 = 432 ≠ 450
Second option: (26, 485)→(26) 2 – 9 = 676 – 9 = 667 ≠ 485
Third option: (13, 160)→(13) 2 – 9 = 169 – 9 = 160
Fourth option: (12, 137)→(12) 2 – 9 = 144 – 9 = 135 ≠ 137

So, only the third option follows the same pattern as followed by the given set of numbers. Hence, the third option is correct.
