a shopkeeper marks his goods 40% above the cost price and allows a discount of 20% on it . what percent does he gain
rachitrajbth:
For this type of questions there is a formula which is a +- b + -A×B/100. Now, 40% is profit so it will be + and 20% is a discount so it will be in minus therefore. 40+(-20)+40×(-20)/100=>40-20-800/100. =>20-8=12%Ans.

Let the cp be 100
so mp is 140
discount is 20%
so selling price will be 80% of 140
=112
so gain % =gain/CP × 100
=12/100×100
=12%
hope it helps

Assume CP = 100
he marks at 40% higher.
So MP = 100+40 = 140
he gives 20% discount on MP
discount = 20% of MP = 140 × 20/100 = 28
SP = MP - discount = 140-28 = 112
Net profit = SP - CP = 112-100 = 12
Profit % = 12/100 × 100 = 12%
he marks at 40% higher.
So MP = 100+40 = 140
he gives 20% discount on MP
discount = 20% of MP = 140 × 20/100 = 28
SP = MP - discount = 140-28 = 112
Net profit = SP - CP = 112-100 = 12
Profit % = 12/100 × 100 = 12%
12%
