If A : B : C = 2 : 3 : 5 and A = x% of (B + C), then x is equal to -

Answer:- 1

Explanation:-

Solution:

Let A = 2k, B = 3k, C = 5k
A = x% of (B + C)
⇒ 2k = x% of (3k + 5k) = x% of 8k

\begin{aligned} \Rightarrow \frac{x}{100} = \frac{2k}{8k} = \frac{1}{4} \\ \Rightarrow x = \frac{100}{4} = 25. \end{aligned}

$\eqalign{ & \Rightarrow \frac{x}{{100}} = \frac{{{\text{2k}}}}{{{\text{8k}}}} = \frac{1}{4} \cr & \Rightarrow x = \frac{{100}}{4} = 25. \cr}$
