The number of chocolate bars that Cindy had in the end is repeated. Make the number of chocolate bars that Cindy had in the end the same. LCM of 1 and 4 is 4.
Number of chocolate bars that Cindy had more than Winnie
= 16 u - 3 u
= 13 u
13 u = 104
1 u = 104 ÷ 13 = 8
Number of chocolate bars that Winnie had at first
= 3 u
= 3 x 8
= 24
Answer(s): 24
