Answer:
Let x,y denot the values of chair&tables
2x+3y= 800----(1)
4x+3y=1000----(2)
__________
- 2x+0 =-200
2x =200
x=200/2
x=100
Then the cost of 3 chairs ,
3(x)=3(100)
the cost of three chairs ie Rs.300
put x=100 in (1)
2(100)+3y=800
200+3y=800
3y=800-200
3y=600
y=600/3
y=200
Then the cost of 3 tables,
3(y)=3(200)
the cost of 3 tables is Rs.600
hope it helps

The cost of table is thrice the cost of chair
- therefore , if chair = x , then table = 3x
so According to question
Chair + table = 800
x+3x = 800
4x = 800
x = 800/4
x = 200 = Cost of chair
3x = 3*200 = 600 = cost of table
