Question : Directions: Select the triad in which the numbers are related in the same way as the numbers of the following triads.
(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.)
6 – 7 – 42
8 –13 –104
Option 1: 5 –15 –125
Option 2: 6 – 4 – 72
Option 3: 12 –11–132
Option 4: 9 – 5 – 24

Correct Answer: 12 –11–132
Solution :
Given:
6 – 7 – 42
8 –13 –104
Multiplication of the first two numbers is equivalent to the third number.
⇒ 6 – 7 – 42→6 × 7 = 42
⇒ 8 –13 –104→8 × 13 = 104
Let's check the options –
First option:
5 –15 –125→5 × 15 = 75 ≠ 125
Second option:
6 – 4 – 72→6 × 4 = 24 ≠ 72
Third option:
12 –11 –132→12 × 11 = 132
Fourth option:
9 – 5 – 24→9 × 5 = 45 ≠ 24
So, only the third option follows the same pattern as followed by the given set of numbers. Hence, the third option is correct.
