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 10 is 10.
Number of files sold
= 20 u - 4 u
= 16 u
16 u = 96
1 u = 96 ÷ 16 = 6
Number of punchers were sold
= 10 u
= 10 x 6
= 60
Answer(s): 60
