Question

After allowjng a discount of 10% on the marked price a trader still makes a gain of 17 % by what per cent is the marked price above the cost price

Answer 1

Let MRP $ 100

then, Discount on MRP = 90

Let C.P be X

then, gain of 17% = 117X/100

so,

$\frac{117x}{100} = 90 \\ x = \frac{90 \times 100}{117} \\ x = \frac{9000}{117} \\ x = \frac{1000}{13} \\ x = 76.92$

C.P = $ 76.92

% =

$76.92 \times \frac{y}{100} = 100 \\ y = \frac{10000}{76.92} \\ y = 130.00$

130 - 100 = 30 %

Market price is 30% more than the cost price.
