The number of jelly beans that Xuan had in the end is repeated. Make the number of jelly beans that Xuan had in the end the same. LCM of 1 and 4 is 4.
Number of jelly beans that Xuan had more than Fanny
= 24 u - 2 u
= 22 u
22 u = 132
1 u = 132 ÷ 22 = 6
Number of jelly beans that Fanny had at first
= 2 u
= 2 x 6
= 12
Answer(s): 12
