At the office building, Storey G and Storey H had an equal number of chairs at first. If 6 chairs were removed from Storey H and 6 times as many chairs were removed from Storey G as Storey H, the number of chairs in Storey H would be 3 times as many as in Storey G. Find the number of chairs on each storey.
| |
Storey G |
Storey H |
| Before |
1 u + 36 |
3 u + 6 |
| Change |
- 36 |
- 6 |
| After |
1 u |
3 u |
Number of chairs removed from Storey G
= 6 x 6
= 36
Number of chairs on Storey G and Storey H at first is the same.
3 u + 6 = 1 u + 36
3 u - 1 u = 36 - 6
2 u = 30
1 u = 30 ÷ 2 = 15
Number of chairs on each storey
= 1 u + 36
= 15 + 36
= 51
Answer(s): 51
