Question

What sum will amount to rupees 6600 in 4 years at 8% per annum simple interest

Answer 1

Hey Mate here is your Ans ❤❤.......

Let the principal be x Rs.

Amount= 6600Rs.

Rate of interest= 8%.

Time= 4years.

S.I=Amount - principal.

(P*R*T)/100= 6600-x.

(x*8*4)/100=6600-x.

32x=(6600-x)100.

32x= 660000- 100x.

100x+32x=660000.

132x=660000.

x=660000/132.

x= 5000Rs.

So Principal= 5000Rs.

Hope it helps.

Answer 2

We recall the concept of simple interest

Simple interest: It is determined by multiplying the interest rate by the principal by the number of days.

Given:

                    $A=6600\\R=8\\T=4$

Simple interest$=\frac{PRT}{100}$

                        $=\frac{32P}{100}$

          Amount is $=P+S.I.$

                $6600=P+\frac{32P}{100}$

                    $P=5000$

Thus principal amount is equal to Rs$5000$
