A trader marked the selling price of an article at 10% above the cost price. At the time of selling, he allows certain discount and suffers a loss of 1%. He allowed a discount of (a) 9% (b) 10% (c) 10.5% (d) 11%

Answer»

(b) 10%

Let the C.P. = Rs 100, M.P. = Rs 110

Loss = 1% \(\Rightarrow\) S.P = Rs \(\big(\frac{99}{100}\times100\big)\) = Rs 99

\(\therefore\) Discount = Rs 110 – Rs 99 = Rs 11

\(\therefore\) Discount percent = \(\big(\frac{11}{110}\times100\big)\)% = 10%
