1 u |
The number of jelly beans that Xandra had in the end is repeated. Make the number of jelly beans that Xandra had in the end the same. LCM of 1 and 4 is 4.
Number of jelly beans that Xandra had more than Yoko
= 28 u - 4 u
= 24 u
24 u = 192
1 u = 192 ÷ 24 = 8
Number of jelly beans that Yoko had at first
= 4 u
= 4 x 8
= 32
Answer(s): 32
