Answer:
18 stamps
Step-by-step explanation:
If the number of stamps Max has is reduced by 36 and Jack's collection remains unchanged, then Max and Jack have the same number of stamps.
Thus, if Max gives Jack (36/2 =) 18 stamps, they will have the same number of stamps.
Max needs to give Jack 18 stamps so they have the same number.

More solution than is required
Since their total of 86 remains unchanged after Jack gets 18 stamps from Max, Jack must start with 86/2 -18 = 25 stamps. Max must have 86-25 = 61 stamps to start with.
