The number of stamps that Kaye and Alberto had were in the ratio of 5:3 respectively. After Kaye gave Alberto 10 of her stamps, the ration of the number of Kaye had to the number of Alberto had was 7:5. As a result of the gift, Kaye had how many more stamps than Alberto?

(A) 20
(B) 30
(C) 40
(D) 60
(E) 90

(C) 40

Step by step explanation:

Let x represent number of stamps.

We have been given that the number of stamps that Kaye and Alberto had were in the ratio of 5:3 respectively.

We can represent this information in an equation as:

We are also told that after Kaye gave Alberto 10 of her stamps, the ration of the number of Kaye had to the number of Alberto had was 7:5.

We can represent this information in an equation as:

Cross multiply:

To find the the number of stamps that Kaye has more than Alberto after giving 10 stamps to Alberto, we will use an expression as:

Therefore, Kaye have 40 stamps more than Alberto and option C is the correct choice.
