Solution

In the end, each of them have 18 picture cards:

54 : 3 = 18 (picture cards)

At first, Billy has 21 picture cards:

18 + 3 = 21 (picture cards)

At first, Paul has 13 picture cards:

18 - 5 = 13 (picture cards)

At first, Leon has 20 picture cards:

54 - (21 + 13) = 20 (picture cards)

Answer: Billy: 21 picture cards

              Paul: 13 picture cards

              Leon: 20 picture cards.
