principal is ₹4520 interest is ₹300 and time is 1 year find A and R?
​

Answer 1

Answer:

Given P = 1200, R = 12%, T = 3 years.

We know that SI = P*R*T/100

                           = 1200 * 12 * 3/100

                           = 43200/100

                           = 432.

We know that Amount = Principal + Interest

                                     = 1200 + 432

                                     = 1632.

The amount to be paid = 1632 rupees.

(b) Given P = 7500, R = 5%, T = 3 years.

We know that SI = PRT/100

                           = 7500 * 5 * 3/100

                           = 112500/100

                           = 1125.

We know that Amount = Principal + Interest

                                     = 7500 + 1125

                                     = 8625.

The amount to be paid = 8625 rupees.

Hope this helps!
