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

Here, x = 40 and y = 30;
Therefore second number
= [[ $\frac{100+y}{100+x}$] x 100 ]% of first number
= [[ $\frac{100+y}{100+x}$] x 100 ]% of first number
Second number = 92.8% of the first number.
