    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.
