Answer 1

Step-by-step explanation:

Let the marked price be 100

Discount at 20% then selling price is

80

He gets 25%profit .Then cost price =80*100/125

Cost price =64

The trader want 40% then

64*40/100=89.6

Then the selling price is 89.6

100–89.6=10.4

The trader must provide 10.4% on marked price to earn 40%profit
