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

148 paise
254 paise
356 paise
472 paise

Answer:- 1

Explanation:-

Solution:

\begin{aligned} Let the required weight be x kg . \\ Less weight, less cost (Direct Proportion) \\ ∴ 250 : 200 :: 60 : x \Leftrightarrow 250 \times x = (200 \times 60) \\ \Rightarrow x = \frac{(200 \times 60)}{250} \\ \Rightarrow x = 48 \end{aligned}

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