Question

calculate the amount and the compound interest by using the formula for compound interest principal to number RS 1,000 rate of interest 10% p. A time in a year 3

Answer 1

A=P(1+r/100)^n
A=1000(1+10/100)³
A=1000(110/100)³
A=1000(11/10)³
A=1000×1331/1000
A=₹1,331

CI=A-P
CI=1331-1000
CI=₹331

Answer 2

amount =1000×110/100×110/100×110/100
=1331rs
ci=1331-1000
=Rs331
