There are certain number of chairs and tables loaded up in the shipping container. All the chairs have equal weight and all the tables have equal weight as well. There are \(6 \) times as many chairs as there are tables. The weight of each table is \(9 \) times the weight of each chair. If the total weight of the tables is \(1,200 \) kilograms, then the total combined weight of the chairs and tables is how many kilograms?
A \(1,500\)
B \(1,800\)
C \(2,000\)
D \(2,400\)
E \(3,000\)

Weight of each chair: x
Weight of each table: y
Furthermore, 99x = y
Number of chairs: c
Number of tables: t
Furthermore, c = 66t ==> t = c/66
Total weight of all tables: t*y = t*(99x) = (c/66)(99x) to put everything in terms of c and x.
This value is 1200kg, so (c/66)(99x) = (99/66)*cx = (3/2)cx = 1200.
It follows that cx = (2/3)1200 = 800
Total weight of all chairs: c*x = 800 -- this is the value we just found above!
Add this cx = 800 to the ty = 1200 and you get 800 + 1200 = 2000. Answer C.
