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.)
(13 – 15 – 7); (9 – 11 – 5)
Option 1: (16 – 24 – 10)
Option 2: (15 – 18 – 9)
Option 3: (26 – 37 – 15)
Option 4: (22 – 45 – 21)

Correct Answer: (16 – 24 – 10)
Solution :
Given:
(13 – 15 – 7); (9 – 11 – 5)
Here, (13 – 15 – 7)→(13 + 15) ÷ 4 = 28 ÷ 4 = 7
(9 – 11 – 5)→(9 + 11) ÷ 4 = 20 ÷ 4 = 5
Let's check the options –
First option:
(16 – 24 – 10)→(16 + 24) ÷ 4 = 40 ÷ 4 = 10
Second option:
(15 – 18 – 9)→(15 + 18) ÷ 4 = 33 ÷ 4 = 8.25 ≠ 9
Third option:
(26 – 37 – 15)→(26 + 37) ÷ 4 = 63 ÷ 4 = 15.75 ≠ 15
Fourth option:
(22 – 45 – 21)→(22 + 45) ÷ 4 = 67 ÷ 4 = 16.75 ≠ 21
So, only the first option follows the same pattern as followed by the given set of numbers. Hence, the first option is correct.
