Question

How much time will it take for Rs 5660 invested at 10 percent p.a. simple interest to amount to Rs 7641

Answer 1

How long will it take for Rs 5660 invested at 10% per annum simple interest to amount to Rs 7641?

Solution.    Here, P = Rs 5660, A = Rs 7641, R = 10% p.a.

               I = A — P = Rs 7641 — Rs 5660 = Rs 1981

               Let T years be the required time.

   Using    T = I∗100P∗R,

we get T = 1981∗1005660∗10

               

               = 1981566

               

                = 72 = 312

           Hence the required time = 312 years = 3 years 6 months.

Answer 2

Answer:

here, P - 5670

R- 10% per annnum

A- 7641

Intrest,Time - ?

I = A- P

7641-5660

1981

T=I×100/ P×R

= 1981×100/5660×10

= 7/2 = 3 1/2

= 3 years 6 month
