Since all the folders were sold, the number of folders at first and the number of folders sold were the same. Make the number of folders at first and sold the same. LCM of 1 and 7 is 7.
Number of correction tapes sold
= 14 u - 2 u
= 12 u
12 u = 96
1 u = 96 ÷ 12 = 8
Number of folders were sold
= 7 u
= 7 x 8
= 56
Answer(s): 56
