If 25% of half of x is equal to 2.5 times the value of 30% of one fourth of y, then x is what percent more or less than y?
Answer & Solution
Correct Answer:
Option
A
$$\eqalign{
& y \times \frac{1}{4} \times \frac{{30}}{{100}} \times 2.5 = x \times \frac{1}{4} \times \frac{1}{2} \cr
& \frac{x}{y} = \frac{3}{2} \cr
& x:y = \underbrace {3\,:\,2}_{ + 1} \cr
& \% = \frac{1}{2} \times 100 = 50\% \cr} $$
