Question

Find the $S.I$ on $\text{Rs.}200$ for $7$ months at $5$ paisa per rupee per month.

Answer 1

Given Principal amount $=Rs.200$

Time period $=7$

Rate of interest $5$ paisa per rupee per month.

So, the interest in one month on $\text{Rs.}200$ will be,

$\begin{array}{cc}S.I& =200\times 5\\ & =1000\text{paisa/month}\\ & =10\text{rupees/month}\end{array}$

So, the interest in $7$ months will be,

$10\times 7=\text{Rs.}70$
