Answer 2

The annual interest is 6.5%

Step-by-step explanation:

Principal = Rs.7800

Time = 7 years

Amount = Rs.11349

Interest = Amount - Principal

Interest = 11349-7800

Interest = 3549

Formula : $SI = \frac{P \times T \times R}{100}$

$3549= \frac{7800 \times 7 \times R}{100}$

$\frac{3549 \times 100}{7800 \times 7}=R$

$6.5\%=R$

Hence The annual interest is 6.5%
