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. – operations on 13 such as adding/subtracting/multiplying etc. 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

17–21–25
Option 1: 19–22–25
Option 2: 34–12–28

Correct Answer: 19–22–25
Solution :
Given:
(15–14–13); (17–21–25)
Divide the sum of the first and the third numbers by 2 to obtain the second number.
(15–14–13)→15 + 13 = 28; 28 ÷ 2 = 14
(17–21–25)→17 + 25 = 42; 42 ÷ 2 = 21
Let's check each option –
First option:
(19–22–25)→25 + 19 = 44; 44 ÷ 2 = 22
Second
option:
(34–12–28)→34 + 28 = 62; 62 ÷ 2 = 31 ≠ 12
Third option:
(38–28–10)→38 + 10 = 48; 48 ÷ 2 = 24 ≠ 28
Fourth option:
(23–42–46)→23 + 46 = 69; 69 ÷ 2 = 34.5 ≠ 42
So, only the first option follows the same pattern as followed by the triads given in the question. Hence, the first option is correct.
