    খ)
    \(13\frac{1}{3}\%\)
    গ)
    \(9\frac{1}{{11}}\%\)
    ঘ)
    \(17\frac{1}{7}\%\)
    ঙ)
    None of these

    Explanation

    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 = ProfitCost  price  ×100=  x396x36  ×100=10011=9111  %.\frac{{Profit}}{{Cost\;price\;}} \times 100 = \;\frac{{\frac{x}{{396}}}}{{\frac{x}{{36}}}}\; \times 100 = \frac{{100}}{{11}} = 9\frac{1}{{11}}\;\% .
