In what time $\mathrm{Rs}.150$ will produce the same interest $8\%$ as $\mathrm{Rs}.800$ produce in $3$years at $4.5\%?$

A man buys a house and pays $₹10,000$ cash and $₹8,800$ at $2$ years credit at $5\%.$ Find the cash price of the house.

The difference between simple interest and compound interest on a certain amount at the rate of $10\%$ Per annum for $2$ years are $\mathrm{Rs}.1.50.$ What is the amount?

$\mathrm{Rs}.10000$ lent at $10\%$ Per annum on compound interest in $4$ years will amount to:

The simple interest on a certain sum at a certain rate in $3$ years are $\mathrm{Rs}.78$ and the compound interest in $2$ years are $\mathrm{Rs}.53.04,$ find the rate.

A certain sum put out at compound interest amounts to $₹8820$ in $3$ years and to $₹9261$ in $4$ years. Find the rate:

Find the difference between Compound Interest and Simple Interest on $₹1000$ in $3$ years at $10\%$ yearly.

The compound interest on a certain sum as $5\%$ in $\frac{3}{2}$ years are $\mathrm{Rs}.91.50.$ Find the simple interest.
