Number of pens that Oscar had before = 10 u
Number of pens that Oscar gave to Japheth = 1 u
Number of pens that Oscar gave to Jenson = 2 u
Number of pens that Oscar gave to Henry = 3 u
Number of pens that Oscar had left = 4 u
4 u = 36
1 u = 36 ÷ 4 = 9
Number of pens that Oscar had at first
= 10 u
= 10 u x 9
= 90
