A shopkeeper marks his goods at 20% above the cost price, but to trick his customers, he offers a 10% discount on the marked price and also uses a faulty weight that weighs 800 g for 1 kg. Find his
overall profit percentage.
Show answer & explanation
Correct answer: D
Explanation
The Correct answer is Option 4 i.e. 35%.
CP : SP
100 : 120
100 : 90
800 : 1000
So, CP : SP = 80 : 108
Profit percentage = [(108 - 80)/80] × 100 = 35%
