Analysis: 1 table+1 chair =600 yuan.
Then: 2 tables +2 chairs =600×2= 1200 yuan.
Two tables = three chairs.
So: 3 chairs +2 chairs = 1200 yuan.
5 chairs = 1200 yuan
600×2÷(3+2)
= 1200÷5
= Chair in 240 yuan at unit price.
600-240 = Table with unit price in 360 yuan.
A: Table 360 yuan, Chair 240 yuan.
