Emily had 220 less lollipops than Usha. Usha used
78 of her lollipops and Emily used
34 of her lollipops. In the end, Usha had 3 times as much as Emily. Find the number of lollipops that Usha had at first.

- 7x3 =

- 3 u |
| After |
1x3 =
3 u |
1 u |
Comparing Usha

3 u |
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 Emily had less than Usha
= 24 u - 4 u
= 20 u
20 u = 220
1 u = 220 ÷ 20 = 11
Number of lollipops that Usha had at first
= 24 u
= 24 x 11
= 264
Answer(s): 264
