The price of an item increased by 20% and then decreased by 20%. The final price as compared to the original price is
A20% less
B20% more
C4% more
D4% less ✓ Correct
Correct answer: (D) 4% less — The final price is 4% less, so that is the answer.
Explanation
★The final price is 4% less, so that is the answer.
★Take the original price as 100.
★A rise of 20 per cent makes it 120.
★A fall of 20 per cent on 120 removes 24, leaving 96.
★So the price falls from 100 to 96.
★That is a decrease of 4 per cent, so the final price is 4% less.
