Question

The annual rate of growth in population of a certain city is 8%. If its present
population is 1,96,830, what was the population three years ago?​

Answer 1

Answer:

population three years ago=X(let)

growth rate=8%

according to question,

X(1+8/100)^3=196830

X•19683/15625=196830

X=156250

so,

population after 3 years is 156250
