Question

a trader marks his goods 40 ℅ above the cost price. he sells them at a discount of 20℅. what is his loss or gain percentage.

Answer 1

Let the C.P. be 100x,

M.P. = 140x, S.P. = (100 - 20) x 140x = 112x,

Profit= 12x and profit%= (12x/100x) x 100 = 12%.

A trader marks his goods for the cost price and it takes a discount of 15% for cash.

If he sells it at the discount, it takes 10% for gaining market price. He actually denotes gain or loss functions.

Answer 2

Given :

A trader marks his goods 40% above the cost price and gives a discount of 20% on the marked price.

To find:

Gain percentage

Solution :

Let the cost price is 100

Finding Marked price -

40% of 100 + 100

= 40 + 100

= 140

Marked Price = 140.  

Finding discount -

Discount on Marked Price.  

Discount % = 20 % (Given)

Discount = 140 x 20/100 = 28

Finding Selling Price -

Selling Price = Marked Price - Discount

Selling Price = 140 - 28

Selling Price = 112.

Finding  Gain -

Gain = Selling Price - Cost Price

Gain = 112 - 100

Gain = 12

Finding Gain Percentage -

Gain % = Gain/Cp x 100

Gain % = 12/100 x 100

Gain % = 12 %.

Hence, Gain Percentage = 12%
