An amount of ₹ $8000$ was deposited at simple interest for $3$ years at $7.5$ $\%$ per annum. How much more would have gained (In ₹) had it been deposited at the same rate per cent compound interest?

Which information given below is sufficient to know the amount if the difference between the $C.I. \& S.I.$ for $2$ years is $18$?

($I$) The rate is same at which an amount of $Rs. 1000$ become $1120$ for $2$ years in $S.I.$

($II$) The principal given is $Rs. 2000$.

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 $\%$)

The simple interest accrued on a certain principal is ₹ $2,000$ in five years at the rate of $4$ percent $p.a.$ What would be the compound interest (In ₹) accrued on the same principal at the same rate in two years?

What would be the compound interest (In $Rs.$) accrued on amount of $Rs. 7400$ @ $13.5$ $p.c.p.a.$ at the end of $2$ years? (rounded off to two digits after decimal)

Divide $Rs. 2602$ between $X$ and $Y$, so that the amount of $X$ after $7 \,yr$ is equal to the amount of $Y$ after $9 \,yr$, the interest being compounded at $4 \%$ pa.
