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?

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 $\%$)

If the rate of interest be $4 \%$ per annum for first year, $5 \%$ per annum for second year and $6 \%$ per annum for third year, then the compound interest of $Rs. 10000$ for $3$ years will be (In $Rs.$)

If the simple interest on a sum of money for $2$ years at $5 \%$ per annum is ₹ $50,$ what is the compound interest (In ₹) on the same sume at the same rate and for the same time?

What will be the compound interest (In ₹) on a sum of ₹ $50000$ after $4$ years at the rate of $10 \%$ per annum?

On a sum of money, the simple interest for $2$ $years$ is ₹ $660$, while the compound interest is ₹ $696.30$, the rate of interest being the same in both the cases. The rate of interest (In $\%$) is
