If a quarter kg of potato costs 60 paise, how many paise will 200 gm cost?

Answer: Option A

$$\begin{array}{rl}& \text{Let}\text{the}\text{required}\text{weight}\text{be}x\text{kg}.\\ & \text{Less}\text{weight,}\text{less}\text{cost}\left(\text{Direct}\text{Proportion}\right)\\ & \therefore 250:200::60:x\\ & \Rightarrow 250\times x=200\times 60\\ & \Rightarrow x=\frac{200\times 60}{250}\\ & \Rightarrow x=48\end{array}$$
