Explanation:
First we find the interest at the end of the first year.
Principal = #600
Rate = 3%
Time = 1 year
Interest =
![(600 * 3 * 1)/(100)](https://img.qammunity.org/2021/formulas/mathematics/high-school/iy5w87h8js57k9w5d7g36857lw2cvmeymx.png)
= #18
Amount = #618 at the end of the first year
Now at the end of the second year.
Principal now = #618
Rate now = 2%
Time = 1 year
Interest =
![(618 * 2 * 1)/(100)](https://img.qammunity.org/2021/formulas/mathematics/high-school/mn2vildrxkvf73wxuxion80sxngpenanqn.png)
= #12.36
Amount = #630.36 at the end of the second year
