Please assist to solve the below

Question 18: Keane bought some marbles and gave half of them to Leon. Leon bought some stamps and gave half of them to Keane. Keane used 5 stamps and Leon gave away 11 marbles. The ratio of the number of stamps to the number of marbles Keane had left then became 1:7 and ratio of the number of stamps to the number of marbles Leon had left became 1:5. How many stamps did Leon buy?
