Peter bought an item at 20% discount on its original price. He sold it with 40% increase on the price he bought it. The new sale price is greater than the original price (in percent) by

Answer 1

Let the original price be 100

His purchase price 80

His selling price 80 * 140/ 100 = 112

This gives 12 percent profit on the original price

Answer 2

Answer: The new  price is 12% greater than the original price

Step-by-step explanation:

Let the original price = Rs. 100

Peter bought it at 20% discount

Therefore peter bought it for $= 100- 20\5 \text { of }100 = 100- 20 = Rs. 80$

Now CP of item = Rs. 80

He sold it at 40% increased price

$SP = CP + 40\5 \text { of }CP = 80+ \dfrac{40}{100} \times 80 = 80 + 32= Rs. 112$

New price is greater than original price by 112- 100 =Rs. 12

Hence, the new  price is 12% greater than the original price
