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 7 is 7.
Number of markers sold
= 14 u - 2 u
= 12 u
12 u = 96
1 u = 96 ÷ 12 = 8
Number of markers at first
= 14 u
= 14 x 8
= 112
Answer(s): 112
