Question

a trader marks his goods 40 % above the cost price he is pulse them at a discount of 5% what is his loss or gain percentage

Answer 1

Answer:

33%

Step-by-step explanation:

Define x:

Let the cost price be x

Find the selling price in term of x:

Profit = 40%

Selling Price = x + 0.4x = 1.4x

Find the discount:

Discount = 5% of 1.4x

Discount = 0.05 x 1.4 = 0.07x

Find the price after discount:

Price = 1.4x - 0.07x = 1.33x

Find the profit/loss

1.33x > x ⇒ It is a profit

Profit = 1.33x - x = 0.33x

Find the profit percentage:

Profit percentage = profit/cost price x 100

Profit percentage = (0.33x ÷ x) x 100 = 33%

Answer: His profit is 33%

Answer 2

Let the C.P. be 100x.
therefore, M.P. = 140x
therefore, S.P.= (100 - 20) x 140x = 112x
therefore, Profit= 12x
Here, profit%= (12x/100x)x 100 = 12%
