The population of country A decreased by p% and the population of country B decreased by q% from the year 2020 to 2021. Here 'p' is greater than ‘q’. Let 'x' be the ratio of the population of country A to the population of country B in the given year.
What is the percentage decrease in 'x' from 2020 to 2021?

A

$$\frac{100(p - q)}{100 - q}$$

B

$$\frac{100(p - q)}{100 + p}$$

C

$$\frac{100(p - q)}{100 - p}$$

D

$$\frac{100(p - q)}{100 + q}$$
