Answer: 31 stamps

Step-by-step explanation:

Given : 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.

Let the number of stamps Alex has be 3x and number of stamps Freddy has be 5x.

Since, together they have 136 stamps.

Then, we have

[tex]3x+5x=136\\\\\Rightarrow\ 8x=136\\\\\Rightarrow\ x=\dfrac{136}{8}=17[/tex]

Thus, No. of stamps Alex has = [tex]3(17)=54[/tex]

No. of stamps Freddy has = [tex]5(17)=85[/tex]

Difference=85-54 =31

Hence, Freddy has 31 stamps more .
