1. We know the initial ratio of the number of stamps. We can represent the initial number of stamps that Kaye and Alberto had, as 5x and 3x resp
2. We can represent the final number of stamps that Kaye and Alberto had as 5x-10 and 3x + 10 resp. The final ratio is 5x-10/3x+10
3. The final ratio is also given as 7:5
4. As (2) and (3) both represent the final ratio of number of stamps and so as both are equivalent we can equate the two. 5x-10/ 3x+10 = 7/5
5. x=30
6. We now need to find out how many stamps Kaye and Alberto had after the gift.
7. Kaye had 5x-10 = 140 stamps. Alberto had 3x-10 = 100 stamps
8. So Kaye has 40 more stamps than Alberto after the gift.
Answer: C
