Answer 1

Simple interest = 2643.75 rupees.

Total amount = 14393.75 rupees.

Answer 2

`\text{We know that the simple interest is given by the formula}\\\\SI=P\cdot r\cdot t\\\\\text{here P is the principle, so }P=2150,\\\\\text{r is the annual interest rate, so }r=11\%=0.11\\\\\text{and t is the time in years, so }t=5\\\\\text{hence usign the above formula, the simple interest is}\\\\SI=2150(0.11)(5)=1182.5 \text{ rupees}\\\\\text{and the total amount is the sum of principle and the interest earned. so}\\\\\text{Total amount}=P+SI=2150+1182.5=3332.5 \text{ rupees}`

Simple Interest = 1182.5 rupees

Total amount = 3332.5 rupees
