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?

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

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