Roshel had the same number of gold, yellow and pink buttons at first.
Total number of buttons in the end
= 1 u + 4 u + 4 u - 31
= 9 u - 31
9 u - 31 = 203
9 u = 203 + 31
9 u = 234
1 u = 234 ÷ 9 = 26
Number of pink buttons that Roshel had at first
= 4 u - 31 + 60
= 4 u + 29
= 4 x 26 + 29
= 133
Answer(s): 133
