A man borrows ₹ $4000$ from a bank at $7 \frac{1}{2} \%$ compound interest. At the end of every year he pays ₹ $1500$ as part repayment of loan and interest. How much does he still owe to the bank after three such instalments (In ₹) ?

Find the difference between $S.I.$ and $C.I.$ (In $Rs.$) at $14 \%$ for $2$ year on $Rs. 10000$

A sum of $Rs. 1000$ after $3 \,years$ at compound interest becomes a certain amount that is equal to the amount that is the result of a $3 \,year$ depreciation from $Rs. 1728$. Find the difference between the rates (In $\%$) of $C.I.$ and depreciation? (Given $C.I.$ is $10 \%$ $p.a.$)

What is the difference between the compound interest and simple interest on ₹ $4000$ at $5 \%$ per annum for $2$ years?

In what time (In $years$) will ₹ $8,000,$ at $3 \%$ annum, produce the same interest as ₹ $6,000$ does in $5$ years at $4 \%$ simple interest?

The simple and compound interests on a sum of money for $2$ years are ₹ $8400$ and ₹ $8652$ respectively. The rate of interest per annum is (In $\%$)
