Number of marbles that Carl had before = 11 u
Number of marbles that Carl gave to Ivan = 2 u
Number of marbles that Carl gave to Neave = 2 u
Number of marbles that Carl gave to Peter = 3 u
Number of marbles that Carl had left = 4 u
4 u = 24
1 u = 24 ÷ 4 = 6
Number of marbles that Carl had at first
= 11 u
= 11 u x 6
= 66
