Given parameters:
Number of chairs = 3
Number of tables = 4
Cost of 3 chairs and 4 tables = Rs 7540
Price of 1 table = Rs220
Unknown:
Price of 1 table = ?
Solution:
Let the cost of 1 table = t
So,
3(220) + 4(t) = 7540
660 + 4t = 7540
4t = 7540 - 660
4t = 6880
t = Rs. 1720
The cost of 1 table is Rs. 1720
