Monica deposited a total of $Rs. 10500$ with a bank in two different deposit schemes at $10 \%$ $p.a.$, interest being compounded annually. As per the schemes, she gets the same amount after $2 \,years$ on the first deposit as she gets after $3 \,years$ on the second deposit. How much money (In $Rs.$) did she deposit for $3 \,years$?

A sum of $Rs. 8448$ is to be divided between $X$ and $Y$ who are respectively $18$ and $19 \,yr$ old, in such a way that if their shares be invested at $6.25 \%$ per annum at compound interest, they will receive equal amounts on attaining the age of $21 \,yr$. The present share of $X$ is (In $Rs.$)

The $S.I.$ is $Rs. 7200$ on $12$ $p.c.p.a.$ for $6$ years on a sum. What is $C.I.$ (In $Rs.$) on $5$ $p.c.p.a$ for $2$ years?

A certain sum of money (In $Rs.$) gives $Rs. 500$ at $5 \%$ S.I. for 1 year. What is the $C.I.$ at the same rate at the end of $2$ years?

Find the ratio of $S.I. \& C.I.$ on a certain sum of money at $5 \%$ per annum for $2$ years

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