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.)

8 – 95 – 11
Option 1: 12 – 144 – 15
Option 2: 17 – 135 – 21

Correct Answer: 6 – 135 – 21
Solution :
Given:
5 – 70 – 9; 8 – 95 – 11
In the above-given triads, add the first and the third numbers, and multiply the resultant by 5 to obtain the second number.
5 – 70 – 9→(5 + 9) × 5 = 14 × 5 = 70
8 – 95 – 11→(8 + 11) × 5 = 19 × 5 = 95
Let's check the options –
First option:
12 – 144 – 15→(12 + 15) × 5 = 27 × 5 = 135
≠ 144
Second option:
17 – 135 – 21→(17 + 21) × 5 = 38 × 5 = 190
≠ 135
Third option:
6 – 135 – 21→(6 + 21) × 5 = 27 × 5 = 135
Fourth option:
4 – 28 – 79→(4 + 79) × 5 = 83 × 5 = 415
≠ 28
So, only the third option follows the pattern of the given triads. Hence, the third option is correct.
