37 of the total number of cupcakes. After baking another 60 apricot cupcakes, the number of apricot cupcakes became
23 of the total number of cupcakes. How many cupcakes did she bake at first?

Total cupcakes |
| Before |
3 u |
4 u |
7 u |
| Change |
+ 60 |
|

| After |
2x4 =
8 u |
1x4 =
4 u |
3x4 =
12 u |
The number of other cupcakes remains unchanged. Make the number of other cupcakes the same. LCM of 4 and 1 is 4.
Number of more apricot cupcakes baked
= 8 u - 3 u
= 5 u
5 u = 60
1 u = 60 ÷ 5 = 12
Number of cupcakes that Neave baked at first
= 7 u
= 7 x 12
= 84
Answer(s): 84
