Question

A dealer marks his goods at 35% above the cost price and allows a discount of 20% on the marked price.find his gain or loss per cent

Answer 1

Sol:
Let the CP of the goods be x.
Marked price of the goods = x + (35/100 of x) = Rs 1.35 x
Discount = 20%
Selling price = MP - Discount
Discount = 20% of 1.35x = 1.35x × 0.2 = Rs 0.27x
SP = 1.35x - 0.27x
SP = Rs 1.08x
Since SP is more than CP, there is a profit.
Profit = SP - Profit
= 1.08x - x
= 0.08x

Profit percentage = (Profit / CP) x 100
= (0.08x / x) x 100
= 8 %

Hope it help!!!

Answer 2

Let the CP of the goods be x.
Marked price of the goods = x + (35/100 of x) = Rs 1.35 x
Discount = 20%
Selling price = MP - Discount
Discount = 20% of 1.35x = 1.35x × 0.2 = Rs 0.27x
SP = 1.35x - 0.27x
SP = Rs 1.08x
Since SP is more than CP, there is a profit.
Profit = SP - Profit
= 1.08x - x
= 0.08x

Profit percentage = (Profit / CP) x 100
= (0.08x / x) x 100
= 8 %
