If the price of a commodity is increased by 10% and 20% successively, what is the net percentage increase/decrease in its price if it is further decreased by 25%?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 1% Decrease.
Let Initial price = 100
Final price = 100 × (110/100) × (120/100) × (75/100) = 99
Net decrease = 100 - 99 = 1%
