Question 11 Mark
On what sum of money does the S.I. for 10 years at 5% become Rs. 1,600?
Answer
$\begin{aligned} & \text { S.I. }=\text { Rs. } 1600, R=5 \% \text { p.a. } T=10 \text { years } \\ & \therefore P=\frac{\text { S.I. } \times 100}{R \times T}=\frac{1600 \times 100}{5 \times 10}=\text { Rs. } 3200\end{aligned}$
