Ques - The price of an item is increased by 20% and then decreased by 20% . The final price as compared to the original price :
(a) 4% more
(b) 20% less
(c) 20% more
(d) 4% less
Solution -
Let,
The Original price = 100
increased in price = 20%
New price = [100 + (20/100) × 100]
= 120
Now,
Decreased in price = 20%
New price = [120 + (20/100) × 120]
= 120 - 24
= 96
Therefore,
Final price = 96
Original price = 100
Difference b/w final price and original price = 96 - 100
= - 4
Hence,
The final price as compared to the original price is 4% less.
