At the office building, Floor G and Floor H had an equal number of tables at first. If 6 tables were removed from Floor H and 3 times as many tables were removed from Floor G as Floor H, the number of tables in Floor H would be 3 times as many as in Floor G. Find the number of tables on each floor.

	Floor G	Floor H
Before	1 u	1 u
Change	- 18	- 6
After	1 u - 18	1 u - 6

Number of tables removed from Floor G
= 3 x 6
= 18

Number of tables on Floor G and Floor H at first is the same.

Number of tables on Floor H is 3 times as many as Floor G in the end. If the number of tables on Floor G increases by 3 times, the number of tables on Floor G and Floor H will be the same.

3(1 u - 18) = 1 u - 6
3 u - 54 = 1 u - 6 
3 u - 1 u = 54 - 6
2 u = 48

1 u = 48 ÷ 2 = 24

Number of tables in each floor
= 1 u
= 24

Answer(s): 24
