2.
(Ans: Rs.15,000/​

Answer 1

Solution given:

principal [P]=P

time [T]=4 years

Rate [R]=13%

compound amount=18900

Simple interest=P-18900

we have

simple interest=
`(P*T*R)/(100)`

P-18900=
`(P*4*13)/(100)`

100P-1890000=52P

48P=1890000

P=1890000/48

P=39375

the sum that amounts =Rs 39375
