Answer 2

At the time of 2 years, The amount Rs. 4500 will become  Rs. 4770 at 3% per annum.

Step-by-step explanation:

Given:

Principal amount (P)= Rs.4500.

Amount after the interest (A)= Rs.4770.

Rate of interest (r)= 3%

To find:

To find the number of years(n).

Solution:

The formula for finding the Interest(I) is = A - P

                                                            = 4770 - 4500

                                                             = Rs.270.

By the simple interest formula (I)= $\frac{P \times N \times R}{100}$

                                                  N = $\frac{I \times 100}{P \times R}$

                                                      = $\frac{270 \times 100}{4500 \times 3}$

                                                      = $\frac{270}{135}$

                                               = 2 years.

After 2 years, The amount Rs. 4500 will become  Rs. 4770 at 3% per annum.
