Pamela and Usha had the
same number of lollipops at first. Pamela gave 12 lollipops away to her brother. In the end, Usha had three times as many lollipops as Pamela. How many lollipops did Pamela have at first?
| |
Pamela |
Usha |
| Before |
3 u |
3 u |
| Change |
- 12 |
|
| After |
1 u |
3 u |
The number of lollipops that Usha had remains unchanged.
Number of lollipops that Pamela gave away
= 3 u - 1 u
= 2 u
2 u = 12
1 u = 12 ÷ 2 = 6
Number of lollipops that Pamela had at first
= 3 u
= 3 x 6
= 18
Answer(s): 18
