Solution

Given, P = Rs. 2000 and R = 6 %
For $1 \frac{1}{2} y r, I = \frac{P \times R \times T}{100} = \frac{2000 \times 6 \times 3}{100 \times 2} = R s . 180$
For 2 yr, $I = \frac{P \times R \times T}{100} = \frac{2000 \times 6 \times 2}{100} = R s . 240$
$∴$ The sum of both interests is Rs.(180 + 240), i.e. Rs.420
