A shopkeeper normally makes a profit of 20% in a certain transaction; he weighs 900 g instead of 1 kg, due to an issue with the weighing machine. If he charges 10% less than what he normally charges, what is his actual profit or loss percentage?
Answer & explanation
Correct answer: option 1
CP SP
Cost 5 6
Quantity 1000 900
————————————
50 : 54
if he charge 10% less means 90% of 50 = 45
Then the profit % = 54 - 45 = 9 × \(\frac{100}{45}\) = 20%
