A firm of readymade garments makes both men's and women's shirts. Its average profit is 6% of the sales. Its profit in men's shirt average 8% of the sales and women's shirts comprise 60% of the output. The average profit per sales rupee in women's shirts is

Answer: Option B

Let the total sales be Rs. x and let the profit in women's shirts average y% of the sales.
Then,
= 8% of 40% of x + y% of 60% of x = 6% of x
$$\begin{array}{rl}& \Rightarrow \frac{8}{100}\times \frac{40}{100}\times x+\frac{y}{100}\times \frac{60}{100}\times x=\frac{6}{100}\times x\\ & \Rightarrow \frac{32}{10}+\frac{6y}{10}=6\\ & \Rightarrow \frac{6y}{10}=\frac{28}{10}\\ & \Rightarrow y=\frac{28}{6}=4.66\end{array}$$
∴ Average profit per sales rupee in women's shirt
$$\begin{array}{rl}& =4.66\%\text{ of Rs}.1\\ & =\text{Rs}.\left(\frac{4.66}{100}\right)\\ & =\text{Rs}\text{. }0.0466\end{array}$$
