Let x = number of stoves & refrigerators sold &

the number of air conditioners = double that of stoves and refrigerators

combined

= 2(x+x)

= 2(2x)

= 4x

Then 600(4x) + 500x+400x = 16 500

2400x + 900x = 16 500

3300x = 16500

x = 16500/3300 = 5

So, x = 5.

Therefore 5 stoves are sold , 5 refrigerators are sold and 20 air conditioners are sold.
