Answer: (3) 92,610
Explanation:-
The present population of a city = 80,000
Growth = 5% per year
The population after one year = 80000 + 80000 x 5/100
= 80000 + 4000 = 84000
The population after two years = 84000 + 84000 x 5/100
= 84000 + 4200
= 88,200
Then, the population after three years =88,200 +  88,200 x 5/100
= 88,200 + 4410
= 92610
Hence, the answer is (3) 92,610.
