Twenty-five percent of Reena's yearly income is equal to seventy-five percent of Anubhav's monthly income. If Anubhav's yearly income is ₹ 240000, what is Reena's monthly income?
(a)₹ 60000
(b)₹ 12000
(c)₹ 5200
(d)Cannot be determined
(e)None of these
Answer
Answer (as printed): E
Explanation
Let Reena's yearly income be ₹ $x$. Anubhav's monthly income $=₹\left(\frac{240000}{12}\right)=₹ 20000$. Then, 25\% of $x=75 \%$ of 20000 $$\begin{aligned} & \Rightarrow \frac{25}{100} x=\frac{75}{100} \times 20000 \\ & \Rightarrow \frac{x}{4}=15000 \Rightarrow x=60000 . \end{aligned}$$
