Answer» Correct Answer - Option 3 : (326, 654, 981)

Out of the four triads three triads follow a pattern

1) (273, 546, 819)

273 = 2 + 7 + 3 = 12

546 = 5 + 4 + 6 = 15

819 = 8 + 1 + 9 = 18

2) (291, 438, 657)

291 = 2 + 9 + 1 = 12

438 = 4 + 3 + 8 = 15

657 = 6 + 5 + 7 = 18

3) (326, 654, 981)

326 = 3 + 2 + 6 = 11

654 = 6 + 5 + 4 = 15

981 = 9 + 8 + 1 = 18

4) (192, 384, 576)

192 = 1 + 9 + 2 = 12

384 = 3 + 8 + 4 = 15

576 = 5 + 7 + 6 = 18

sum of digits of first number in triad is 12

sum of digits of second number in triad is 15

and, sum of digits of third number in triad is 18

on checking, option 3

the first number 326 = 3 + 2 + 6 = 11

654 = 6 + 5 + 4 = 15

981 = 9 + 8 + 1 = 18

Hence, option 3 is different from the given number triads.
