Question

The present population of State P is 3 times the present population of State Q. If after 2 years, the population of State Q will be 18.513 increasing at a rate of 10%
per year, what is the present population of State P ?​

Answer 1

Let the present population of city Q = x

=> x =

${(1 + 10 \div 100)}^{2}$

=18513

=> X × 121÷100

=18513

=> x = 15300

∴ Present population of city P = 15300 * 3 = 45900
