Correct Answer: 8 : 128
Solution :
Given:
5 : 50; 12 : 288
Here, 5 : 50→(5)
2
× 2 = 25 × 2 = 50
12 : 288→(12)
2
× 2 = 144 × 2 = 288
Let's check the options –
First option:
4 : 36→(4)
2
× 2 = 16 × 2 = 32 ≠ 36
Second option:
8 : 128→(8)
2
× 2 = 64 × 2 = 128
Third option:
9 : 161→(9)
2
× 2 = 81 × 2 = 162 ≠ 161
Fourth option:
6 : 70→(6)
2
× 2 = 36 × 2 = 72 ≠ 70
So, only the second option follows the given pattern. Hence, the second option is correct.
