Answer 2

Principal (P)=₹75000
Case¹,
Time(T)=2years
Rate of interest(ROI)=15%
Case²,
Time(T')=1years
Rate of interest (ROI')=16%
:. compound interest (CI)
(equation)
=P(1+r/)(1+r/)(1+r'/)
:. putting value
=75000(1+15/)(1+15/)(1+16/)
=75000(/+15/)(/+15/)(/+16/)
=75000(115/)(115/)(116/)
=75000(23/20)(23/20)(29/25)
=₹115057.5
