Jack and Fred had 48 macarons altogether. After Jack ate
14 of his macarons and Fred ate 8 macarons, the number of macarons Fred had left was twice the number of macarons Jack had left. How many more macarons did Fred have than Jack at first?

Before |

Change |
- 1 u |
- 8 |

After |
3 u |

Comparing Jack and Fred in the end |
1x3 = 3 u |
2x3 = 6 u |
|
The number of macarons that Jack had in the end is the same. Make the number of macarons that Jack had in the end the same. LCM of 3 and 1 is 3.
Total number of macarons at first
= 4 u + 6 u + 8
= 10 u + 8
10 u + 8 = 48
10 u = 48 - 8
10 u = 40
1 u = 40 ÷ 10 = 4
Number of macarons that Jack had at first
= 4 u
= 4 x 4
= 16
Number of macarons that Fred had at first
= 48 - 16
= 32
Number of macarons that Fred had more than Jack at first
= 32 - 16
= 16
Answer(s): 16
