The number of lollipops that Yoko had in the end is repeated. Make the number of lollipops that Yoko had in the end the same. LCM of 1 and 4 is 4.
Number of lollipops that Yoko had more than Zara
= 32 u - 5 u
= 27 u
27 u = 162
1 u = 162 ÷ 27 = 6
Number of lollipops that Zara had at first
= 5 u
= 5 x 6
= 30
Answer(s): 30
