Albert invested an amount of ₹ $8000$ in a fixed deposit scheme for $2$ years at compound interest rate of $5 \%$ per annum. How much amount (In ₹) will Albert get on maturity of the fixed deposit?

Aditya invested certain amount in two different schemes $A$ and $B$. Scheme $A$ offer $S.I$ @ $12$ $p.c.p.a.$ and scheme $B$ offer $C.I.$ @ $10$ $p.c.p.a.$ Interest accured on the amount invested in scheme $A$ in $2$  years was $Rs. 3600$ and the total amount invested was $Rs. 35000$. What was the interest accured on the amount (In $Rs.$) invested in scheme $B$?

What is $C.I.$ (In $Rs.$) on $Rs. 7500$ for $4$ years if the rate of interest is $10 \%$ p.a. for the first $2$ year and $20 \%$ $p.a.$ for the next $2$ year?

The difference between the compound interest and simple interest on a certain sum at $5 \%$ for $2$ years is ₹ $1.50$. The sum is (In ₹) 

In how many $years$ will a sum of ₹ $800$ at $10 \%$ per annum compounded semi-annually become ₹ $926.10$?

The compound interest on a certain sum of money for $2$ years at $5 \%$ per annum is ₹ $410 .$ The simple interest (In ₹) on the same sum at the same rate and for the same time is
