Question

Match each of the entries in Column I with the appropriate entries in Column II.
$\begin{array}{ccc}& & \\ \text{Column I}& & \text{Column II}\\ \text{Interest when principal = Rs.800}& \text{K.}& 20\%\\ \text{rate of Interest = 10}\%\text{per annum and period = 2yr}& & \end{array}$

Answer 1

$\to \left(D\right)$
Given, P = Rs. 800, R = 10 \%, T = 2 yr I = ?
$\therefore I=\frac{\text{P}\times \text{R}\times \text{T}}{100}=\frac{800\times 10\times 2}{100}=160=\text{Rs.}160$
