A bus company increas the price of all ticket by 6%

Question

A bus company increas the price of all ticket by 6% Before the increase, the price of a ticket from Cork to Dublin was €17.00 find the price of this ticket after the increase. Six months later the company reduces the price of this ticket back to€17.00, find the percentage decrease in the price of the ticket

Answer 1

If you increase by 6%, you now have 106%.

 

1.06(17) = 18.02

 

Now, taking it back to 17 is not taking 6% off, because 6% of 18.02 is more than 6% of 17.

 

Percent increase or decrease = difference/original price

 

1.02/18.02 = 0.0566 = 5.7%
