→ Population of city after 4 years = current population * [1 - (Rate/100)]^Time

→ Required population = 9500000[1 - (20/100)]⁴

→ Required population = 9500000[1 - (1/5)]⁴

→ Required population = 9500000 * (4/5)⁴

→ Required population = 9500000 * (256/625)

→ Required population = 3891200 (Ans.)
