Correct Answer: 12 : 81 : 63
Solution :
Given:
11 : 87 : 34
6 : 28 : 8
⇒ 11 : 87 : 34→11
2
= 121; 87 + 34 = 121
⇒ 6 : 28 : 8→6
2
= 36; 28 + 8 = 36
Let's check each option –
First option:
9 : 25 : 54; 9
2
= 81; 25 + 54 = 79; 81 ≠ 79
Second option:
7 : 35 : 12; 7
2
= 49; 35 + 12 = 47; 49 ≠ 47
Third option:
8 : 19 : 47; 8
2
= 64; 19 + 47 = 66; 64 ≠ 66
Fourth option:
12 : 81 : 63; 12
2
= 144; 81 + 63 = 144
So, the fourth option follows the same pattern. Hence, the fourth option is correct.
