Question

What will be the compound interest earned on an amount of Rs.12000/- @ 10 p.c.p.a. in two years?​

Answer 1

Step-by-step explanation:

Hope this helps you :-

Here P=12,000 Rs., n=2 years, R=10

Amount(A)=P(1+100R)n

                     =12000(1+10010)2

                     =12000(1011)2

                     =10012000×121

                     =14,520 Rs.

Compound interest(C.I)=A−P=14,520−12,000=2520

Answer 2

C.I. = P [(1+R100)T−1]

= 7790 [(1+10100)2−1]

= 7790 (121100−1)

= 7790×21100 = Rs.1635.9
