a shopkeeper bought an article at 20% discount on the marked price and he sold it at a profit of 40% on the marked price. what is the actual profit% made by the shopkeeper??
Answers
Step-by-step explanation:
let,
market price of article be x
discount = x * 20/100
= 20x/100
cost price = x - 20x/100
= 100x - 20x
100
= 80x
100
= 8x/10
profit = 8x/10 * 40/100
= 8x/10 * 4/10
= 32x/100
sold price = 8x/10 + 32x/100
= 80x/100 + 32x/100
= 112x/100
actual profit = 112x/100 - x
= 112x - 100x
100b
= 12x/100
actual profit in % = 12x/100 * 100
x
= 12x. * 100
100x
= 12%
