1 u |
The number of lollipops that Usha had in the end is repeated. Make the number of lollipops that Usha had in the end the same. LCM of 1 and 3 is 3.
Number of lollipops that Usha had more than Tina
= 18 u - 5 u
= 13 u
13 u = 65
1 u = 65 ÷ 13 = 5
Number of lollipops that Tina had at first
= 5 u
= 5 x 5
= 25
Answer(s): 25
