If 25% of A = 20% of B = 10% of C, find A : B : C.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 4 : 5 : 10.
Let 25% of A = 20% of B = 10% of C = k
⇒ 25A/100 = 20B/100 = 10C/100 = k
⇒ A/4 = B/5 = C/10 = k
A = 4k, B = 5k, C = 10k
A : B : C = 4k : 5k : 10k = 4 : 5 : 10
