Question

the price of item was increased by 20%the results was decreased by 5%.find the total increase in percentage

Answer 1

If the price of an item increases by a%, then its new price will be (100 + a)%

If the price of an item decreases by a%, then its new price will be (100 - a)%

Let the price of the item be 100%

Since it was increased by 20%, then

The new price = (100 + 20)% = 120%

Since this new price was decreased by 5%, then

That means the last price will be (100 - 5)% = 95% of the new price

Last price = 95% of 120%

`(95)/(100)*(120)/(100)*100=114`

The last price is 114% of the original price

Since 114% - 100% = 14%

The total increase is 14%
