The number of lollipops that Kathy had in the end is repeated. Make the number of lollipops that Kathy had in the end the same. LCM of 1 and 4 is 4.
Number of lollipops that Roshel had less than Kathy
= 24 u - 4 u
= 20 u
20 u = 160
1 u = 160 ÷ 20 = 8
Number of lollipops that Kathy had at first
= 24 u
= 24 x 8
= 192
Answer(s): 192
