Answer 2

Burger Queen's fries are 40% cheaper than Mac Tiger's

Step-by-step explanation:

Given: Burger Queen advertises “Our French fries is 25% larger than Mac Tiger’s fries at a price 25% less than Mac Tiger’s”.

Find: For the same size, by how much in percentage are Burger Queen’s fries cheaper than Mac Tiger’s?

Solution: Let Burger Queen fries be B and Mac Tiger fries be M.

Given that B is 25% larger than M.

So B = M + 25/100 M (size)

     4B = 5M

     4/5B = M ----------(1)

Price of B = M - 25% = M - M/4 = 3/4M

So Price of B at the same size as M = 4/5 * 3/4 = 3/5

  In percentage = 3/5 * 100 = 60%

Hence Burger Queen's fries are 40% cheaper than Mac Tiger's for the same size.
