Since all the punchers were sold, the number of punchers at first and the number of punchers sold were the same. Make the number of punchers at first and sold the same. LCM of 1 and 5 is 5.
Number of glues sold
= 30 u - 4 u
= 26 u
26 u = 260
1 u = 260 ÷ 26 = 10
Number of punchers were sold
= 5 u
= 5 x 10
= 50
Answer(s): 50
