Find the amount to be paid at the end of 1 year on ₹ 1,800 at 8% per annum compounded quarterly.

Principal = ₹ 1,800

There are 4 quarters in 1 year.

Therefore, compounding has to be done in 4 times.

Rate of interest = quarter of 8% = 2% quarterly.

$\mathrm{A}=\mathrm{P}{\left(1+\frac{\mathrm{R}}{100}\right)}^{\mathrm{n}}$

$=₹ 1800{\left(1+\frac{2}{100}\right)}^4$

$=₹ 1800{\left(1+0.02\right)}^4$

$=₹ 1948.377$

Therefore, the amount to be paid at the end of 1 year on ₹ 1,800 at 8% per annum compounded quarterly is ₹ 1948.377.
