A dishonest shopkeeper defrauds to the extent of P% in buying as well as selling goods by using false weight. Find his profit percent?
Answer & explanation
Correct answer: option 3
Let the actual weight = 100
Weight at the time of buying = (100+P)
Weight at the time of selling = (100 - P)
Profit % = \(\frac{(100 + P - 100 + P)}{100 - P}\) x 100
= \(\frac{200P}{100 - P}\)%
