6 : 646 :: 5 : ? :: 4 : 190
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 373
6 : 646 :: 5 : ? :: 4 : 190
The logic followed here is:
63 × 3 - 2 = 216 × 3 - 2 ⇒ 648 - 2 = 646
43 × 3 - 2 = 64 × 3 - 2 ⇒ 192 - 2 = 190
Similarly,
53 × 3 - 2 = 125 × 3 - 2 ⇒ 375 - 2 = 373
