Bimal sells his cloth at its cost price but instead of 36cm length he uses 33cm long length. Find his profit percentage?
Solution
Correct Answer: Option C
Let his cost price and selling price be Rs. x.
∴ His cost price for 36cm is Rs. x
∴ His cost price for 1 cm = Rs. x/36
He sells 33cm for Rs. x
∴ His Selling price for 1cm = Rs. x/33
∴ Profit = Selling price – Cost price
∴ Profit = x/33 – x/36 = 3x/1188 = x/396
Now, profit percentage = \(\frac{{Profit}}{{Cost\;price\;}} \times 100 = \;\frac{{\frac{x}{{396}}}}{{\frac{x}{{36}}}}\; \times 100 = \frac{{100}}{{11}} = 9\frac{1}{{11}}\;\% .\)
