Nora had 27 more lollipops than Ahmad at first. After Ahmad had eaten 21 of his lollipops, Nora had 5 times as many lollipops as Ahmad. How many lollipops did Nora and Ahmad have in total at first?

Ahmad |
Total |
| Before |
1 u + 21 + 27 |
1 u + 21 |
6 u + 21 |
| Change |
|
- 21 |
|
| After |
5 u |
1 u |

The number of lollipops that Nora had at first remains unchanged.
5 u = 1 u + 21 + 27
5 u - 1 u = 48
4 u = 48
1 u = 48 ÷ 4 = 12
Number of lollipops that they had at first
= 6 u + 21
= 6 x 12 + 21
= 72 + 21
= 93
Answer(s): 93
