If A : B : C = 2 : 3 : 5 and A = x% of (B + C), then x is equal to -
A. 20
B. 24
C. 25
D. 28
Answer: Option C
Solution(By Examveda Team)
Let A = 2k, B = 3k, C = 5kA = x% of (B + C)
⇒ 2k = x% of (3k + 5k) = x% of 8k
$$\eqalign{ & \Rightarrow \frac{x}{{100}} = \frac{{{\text{2k}}}}{{{\text{8k}}}} = \frac{1}{4} \cr & \Rightarrow x = \frac{{100}}{4} = 25 \cr} $$
