Question

A sum amounts to Rs. 2,652 in 6 years at 5% p.a. simple interest. Find :

(i) the sum.

Answer 1

Answer:(i)A=2652,T=6,R=5%

A=P(100100+TR)

P=100+TRA×100

P=100+6×52652×100

P=1302652×100

P=Rs.2040

(ii)P=Rs.2040,A=4080,R=5%

I=A−P

I=4080−2040

I=2040

T=PRI×100

T=2040×52040×100

T=20 yr
