Question 94

Two numbers are 40% and 50% lesser than a third number. By how much percent is the second number to be enhanced to make it equal to the first number?

Solution

Let third number = $$100x$$

First number is 40% less than $$100x$$ and second number is 50% less than $$100x$$

=> First number = $$60x$$ and Second number = $$50x$$

To make second number equal to first number, it should be enhanced by = $$60x - 50x = 10x$$

=> Required % = $$\frac{10x}{50x} \times 100 = 10 \times 2 = 20 \%$$

=> Ans - (B)
