Question

The population of a town was 2,00,000 in the year 2020. it increases at the rate of 5% per annum then what would be its population in the year 2023.

Answer 1

Step-by-step explanation:

5 percent increase for 3 years

For 2 consecutive increase = x+y+xy/100

For first 2 yrs percentage increase = 5+5+25/100= 10.25%

For 3 yrs

percentage increase = 10.25 + 5 + 10.25*5/100 = 15.7625%

population increase for 3 yrs = 31525

Total population in 2023 = 200000+31525 = 231525
