Eva baked 32 puffs.
58 of the puffs were mango puffs. The rest were vanilla puffs. She gave an equal number of mango puffs and vanilla puffs away and had 2 times as many mango puffs as vanilla puffs left. How many puffs did she give away?

Mango puffs |
Vanilla puffs |
Difference |
| Before |
5x1 =
5 u |
3x1 =
3 u |
2x1 =
2 u |
| Change |
- 1 u |
- 1 u |
|
| After |
2x2 =
4 u |
1x2 =
2 u |
1x2 =
2 u |
Since Eva gave away an equal number of mango puffs and vanilla puffs, the difference in the number of mango puffs and vanilla puffs remains unchanged. Make the difference in the mango puffs and vanilla puffs the same. LCM of 2 and 1 is 2.
Total number of puffs at first
= 5 u + 3 u
= 8 u
8 u = 32
1 u = 32 ÷ 8 = 4
Number of puffs that Eva gave away
= 1 u + 1 u
= 2 u
= 2 x 4
= 8
Answer(s): 8
