Question

A trades made allows a discount of 15% on the markes price .How much above the cost price must he mark his goods so to gain 19%?

Answer 1

Hello,

Here,

r =15% and R = 19%

Therefore,

Required percentage is:-

= (r+R/100−r) × 100

= 15+19/100−15 × 100%

= 34×100/85%

= 40%

Thank you!

Answer 2

Heya....!

Solution: 

Let the cost price be $ 100. 

Then, marked price = $ 140. 

Discount = 25% of Marked Price 

                = (25% of $ 140) 

                = $ {140 × (25/100) 

                = $ 35. 

Selling price = (marked price) - (discount) 

                      = $ (140 - 35) 

                      = $ 105. 

Gain% = (105 - 100) % = 5%. 

Hence, the trader gains 5%.
