Two numbers are respectively 40% and 30% more than a third number. The second number expressed in terms of percentage of the first is ?

A 92.8%

B 84.23%

C 87.14%

D 94.1%

Correct Answer: Option A

Here, x = 40 and y = 30;
Therefore second number

= [[ $\frac{100+y}{100+x}$ ] x 100 ]% of first number

= [[ $\frac{100+y}{100+x}$

$\frac{100 + y}{100 + x}$ ] x 100 ]% of first number
Second number = 92.8% of the first number.
