Mr. Kumar borrowed $₹15,000$ for $2$years. The rate of interest for the two successive years are $8\%$ and $10\%$ respectively. If he repays $₹6,200$ at the end of the first year, find the outstanding amount at the end of the second year. Give the answer in $₹$.

In $k$ years $₹12,000$ yield $₹3,972$ as compound interest at $10\%$ per annum, if compounded on an yearly basis, then find the value of $k$.
 

On what sum of money will the difference between the compound interest and simple interest for $2$ years be equal to $₹25$ if the rate of Interest charged for both is $5\%$? Give the answer in $₹$.

A sum of $₹12,000$ deposited at compound interest becomes double after $5$ years. After$20$years, it will become

The difference between $\mathrm{C}.\mathrm{I}.$ (compound interest) and $\mathrm{S}.\mathrm{I}.$ (simple interest) on a sum of $₹4,000$ for$2$ years at$5\% \mathrm{p}.\mathrm{a}$. payable yearly is

If the difference between simple interest and compound interest on a certain sum of money for $3$ years at $10\%$ per annum is $₹31$, the sum is

On what sum of money will compound interest for $2$ years at $5\%$ per annum amount to $₹164$?

A sum of money becomes eight times in $3$ years. If the rate is compounded annually, in how much time will the same amount at the same compound rate become sixteen times?
