Min had twice the number of wooden bricks as George. Min used all her bricks to build 10 identical figurines. George used all his bricks to build 6 identical figurines. Min used 9 more bricks than George for each figurine. How many bricks did George have?

| Number |
10 |
6 |
| Value |
1 u + 9 |
1 u |
| Total value |
10 u + 90 |
6 u |
Number of wooden bricks that George used for each figurine = 1 u
Number of wooden bricks that Min used for each figurine = 1 u + 9
Number of wooden bricks that George had
= 6 x 1 u
= 6 u
Number of wooden bricks that Min had
= 10 x (1 u + 9)
= 10 u + 90
Min had twice the number of wooden bricks as George.
2 x 6 u = 10 u + 90
12 u = 10 u + 90
12 u - 10 u = 90
2 u = 90
1 u = 90 ÷ 2 = 45
Number of bricks that George had
= 6 u
= 6 x 45
= 270
Answer(s): 270
