Question

Two numbers are respectively 40% and 50% of a third number. What percentage is first number of the second?

• A. 90%
• B. 75%
• C. 80%
• D. 60%

Answer 1

The correct option is C

80%

Let the number be 100

First number = $\frac{40}{100}\times$ 100 = 40

Second number = $\frac{50}{100}\times$ 100 = 50

$\therefore$ Comparing first and second number we get : $\frac{40}{50}\times$ 100 = 80%

$\therefore$ The first number is 80% of the second number.
