Question : Directions: Select the triad from the below options that have the same analogy as 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.)
3 : 26 : 8
7 : 342 : 20

Option 1: 2 : 9 : 5

Option 2: 5 : 123 : 14

Option 3: 6 : 216 : 17

Correct Answer: 4 : 63 : 11


Solution : Given:
(3 : 26 : 8); (7 : 342 : 20)

Here, (3 : 26 : 8)→(3) 3 – 1 = 27 – 1 = 26; (3 × 3) – 1 = 9 – 1 = 8
(7 : 342 : 20)→(7) 3 – 1 = 343 – 1 = 342; (7 × 3) – 1 = 21 – 1 = 20

Let's check the options –
First option: (2 : 9 : 5)→(2) 3 – 1 = 8 – 1 = 7 ≠ 9; (2 × 3) – 1 = 6 – 1 = 5
Second option: (5 : 123 : 14)→(5) 3 – 1 = 125 – 1 = 124 ≠ 123; (5 × 3) – 1 = 15 – 1 = 14
Third option: (6 : 216 : 17)→(6) 3 – 1 = 216 – 1 = 215 ≠ 216 and (6 × 3) – 1 = 18 – 1 = 17
Fourth option: (4 : 63 : 11)→(4) 3 – 1 = 64 – 1 = 63; (4 × 3) – 1 = 12 – 1 = 11

So, only the fourth option follows the same pattern as followed by the given set of numbers. Hence, the fourth option is correct.
