The number of lollipops that Nora had in the end is repeated. Make the number of lollipops that Nora had in the end the same. LCM of 1 and 2 is 2.
Number of lollipops that Pamela had less than Nora
= 12 u - 2 u
= 10 u
10 u = 100
1 u = 100 ÷ 10 = 10
Number of lollipops that Nora had at first
= 12 u
= 12 x 10
= 120
Answer(s): 120
