If 40% of A = 0.5 of B = 1/4 of C, then what is A : B : C?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 5 : 4 : 8.
40% of A = 0.5B = (1/4)C = k
⇒ 40A/100 = 5B/10 = (1/4)C = k
⇒ 2A/5 = B/2 = C/4 = k
A = 5k/2, B = 2k, and C = 4k
A : B : C = (5k/2) : 2k : 4k = 5k : 4k : 8k = 5 : 4 : 8
