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.) (36, 24, 65) (40, 54, 19)
Option 1: (10, 21, 321)
Option 2: (20, 18, 16)
Option 3: (13, 8, 98)
Option 4: (30, 14, 56)

Correct Answer: (20, 18, 16)
Solution : Given: (36, 24, 65); (40, 54, 19)
The pattern followed here is – (36, 24, 65) = {(36 ÷ 4) + (24 ÷ 6)} × {(36 ÷ 4) – (24 ÷ 6)} = {9 + 4} × {9 – 4} = 13 × 5 = 65 (40, 54, 19) = {(40 ÷ 4) + (54 ÷ 6)} × {(40 ÷ 4) – (54 ÷ 6)} = {10 + 9} × {10 – 9} = 19 × 1 = 19 Let's check the options – First Option: (10, 21, 321) = {(10 ÷ 4) + (21 ÷ 6)} × {(10 ÷ 4) – (21 ÷ 6)} = {2.5 + 3.5} × {2.5 – 3.5} = 6 × –1 = –6 ≠ 321 Second Option: (20, 18, 16) = {(20 ÷ 4) + (18 ÷ 6)} × {(20 ÷ 4) – (18 ÷ 6)} = {5 + 3} × {5 – 3} = 8 × 2 = 16 Third Option: (13, 8, 98) = {(13 ÷ 4) + (8 ÷ 6)} × {(13 ÷ 4) – (8 ÷ 6)} = {3.25 + 1.33} × {3.25 – 1.33} = 4.58 × 1.92 = 8.7936 ≠ 98 Fourth Option: (30, 14, 56) = {(30 ÷ 4) + (14 ÷ 6)} × {(30 ÷ 4) – (14 ÷ 6)} = {7.5 + 2.33} × {7.5 – 2.33} = 9.83 × 5.17 = 50.8211 ≠ 56
So, only the second option follows the same pattern as followed by the given set of numbers. Hence, the second option is correct.
