The correct option is (B): 50\(\%\)
Explanation:
Let CP of 1 m of cloth = Rs. \(x\) and SP = Rs. \(y\)
Profit on selling 1 m cloth = Rs. (y - x)
According to ques,
⇒ 33(\(y\) - \(x\)) = 11\(y\)
⇒ З\(y\) - 3\(x\) =\(y\)
⇒\(2y=3x\)
⇒\(\frac{x}{y}=\frac{2}{3}\)
Let \(x\) = 2 and \(y\) = 3
\(\therefore\) Profit \(\%\) = \(\frac{y-x}{x}\times100\)
\(=\frac{3-2}{2}\times100\)
\(=50\%\)
