(a)₹ 1200
(b)₹ 2400
(c)₹ 3000
(d)₹ 3200
Answer
Explanation
Let the monthly income be ₹ $x$. Then, $$\begin{aligned} & \left(100-66 \frac{2}{3}\right) \% \text { of } x=1200 \\ & \Leftrightarrow 33 \frac{1}{3} \% \text { of } x=1200 \\ & \Leftrightarrow \frac{100}{3} \times \frac{1}{100} \times x=1200 \\ & \Leftrightarrow x=1200 \times 3=3600 . \\ & \therefore \text { Monthly expenses }=₹(3600-1200)=₹ 2400 . \end{aligned}$$
