Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following set.
(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 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed.)

Correct Answer: (4, 1, 125)


Solution : Given:
(5, 4, 405); (7, 3, 500)

Like, (5, 4, 405)→(5 + 4) 2 × 5 = (9) 2 × 5 = 81 × 5 = 405
(7, 3, 500)→ (7 + 3) 2 × 5 = (10) 2 × 5 = 100 × 5 = 500

Let's check the options –
First option: (4, 1, 125)→(4 + 1) 2 × 5 = (5) 2 × 5 = 25 × 5 = 125
Second option: (3, 2, 145)→(3 + 2) 2 × 5 = (5) 2 × 5 = 25 × 5 = 125 ≠ 145
Third option: (4, 5, 850)→(5 + 4) 2 × 5 = (9) 2 × 5 = 81 × 5 = 405 ≠ 850
Third option: (5, 8, 789)→(5 + 8) 2 × 5 = (13) 2 × 5 = 169 × 5 = 845 ≠ 789

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