What is the present worth of ₹ 132 due in 2 years at 5\% simple interest per annum?
(a)₹ 112
(b)₹ 118.80
(c)₹ 120
(d)₹ 122
Answer
Explanation
Let the present worth be ₹ $x$. Then, S.I. $=₹(132-x)$. $$\begin{aligned} \therefore \quad\left(\frac{x \times 5 \times 2}{100}\right)=132-x & \Leftrightarrow 10 x=13200-100 x \\ & \Leftrightarrow 110 x=13200 \Leftrightarrow x=120 . \end{aligned}$$
