A. 40% of Y

B. 24.5% of Y

C. 50% of X

D. 24.5% of X

Answer: Option D

Solution(By Examveda Team)

$$\eqalign{ & \frac{{X \times 49}}{{100}} = Y \cr & \frac{X}{Y} = \frac{{100}}{{49}} \cr & 50 \times Y\% \cr & = \frac{{2 \times 50 \times 49\% }}{2} \cr & = \frac{{100 \times 49\% }}{2} \cr & = X \times 24.5\% \cr} $$
