If 31 : 52 = 4836 and 18 : 4 = 216, then what is the value of 51 : 27?
Show answer & explanation
Correct answer: B
Explanation
Just as
31 : 52 = 4836
31 × 52 = 1612
1612 × 3 = 4836
and
18 : 4 = 216
18 × 4 = 72
72 × 3 = 216
Rule:
(a:b) = (a × b) × 3
Similarly,
51 : 27
51 × 27 = 1377
1377 × 3 = 4131
Answer: 4131
