(1) the amount credited in his account at the end of 2 years.
(ii) the interest he got in the 3rd year​

Answer 1

Step-by-step explanation:

For first year:

Principal= Rs. 100000

Rate=13% p.a.

Time=1 year

Interest=P×R×T/100

=100000×13×1/100

=Rs 13000

Amount at the end of first year=Principal+Interest

=100000+13000

=Rs 113000

For second year:

Principal=113000 (Amount of the first year)

Rate=13% p.a.

Time=1 year

Interest=P×R×T/100

=113000×13×1/100

=Rs. 14690

Amount at the end of second year=113000+14690

=127690

For third year:

Principal=127690

Rate=13%

Time=1 year

Interest= 127690×13×1/100

=Rs. 16599.7

1. Amount credited in Rinku's account at the end of 2 years= Rs. 127690
2. Interest he got in the third year=16599.7
