Question: A merchant selling 44 meters of cloth obtains a profit equal to the selling price of 11 meters of cloth, the profit is = ?

Solution:
Profit = selling price of 11 m of cloth = 1/4 selling price of 44 m of cloth

Let the selling price of 44 meters of cloth = 4x
∴ profit = (1/4) × (4x) = x

So, cost price = selling price - profit = 4x - x = 3x

% Profit = (x/3x) × 100% = 33.33%
