Number of pens that Ian had before = 11 u
Number of pens that Ian gave to Justin = 2 u
Number of pens that Ian gave to Pierre = 2 u
Number of pens that Ian gave to Xavier = 1 u
Number of pens that Ian had left = 6 u
6 u = 24
1 u = 24 ÷ 6 = 4
Number of pens that Ian had at first
= 11 u
= 11 u x 4
= 44
