Question : Directions: 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 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Option 1: (12, 5, 89)
Option 2: (11, 10, 128)

Correct Answer: (4, 5, 29)
Solution :
Given:
(10, 5, 65); (9, 8, 89)
Here, (10, 5, 65)→(10 × 5) + (10 + 5) = 50 + 15 = 65
(9, 8, 89)→(9 × 8) + (9 + 8) = 72 + 17 = 89
Let's check the options –
First option:
(12, 5, 89)→(12 × 5) + (12 + 5) = 60 + 17 = 77 ≠ 89
Second option:
(11, 10, 128)→(11 × 10) + (11 + 10) = 110 + 21 = 131 ≠ 128
Third option:
(4, 5, 29)→(4 × 5) + (4 + 5) = 20 + 9 = 29
Fourth option:
(8, 7, 98)→(8 × 7) + (8 + 7) = 56 + 15 = 71 ≠ 98
So, only the third option follows the same pattern as followed by the given set of numbers. Hence, the third option is correct.
