Alex and Freddy collect stamps. The number of stamps in Alex’s collection to the number of stamps in Freddy’s collection is in the ratio of 3:5. How much more stamps does Freddy have if together they have 136 stamps?

Answer provided by our tutors

Alex has: 'x' stamps

Freddy has: 'y' stamps

We need to find 'y - x'.

x : y = 3 : 5 cross-multiply

5x = 3y

x + y = 136
