Question

The total cost of 5 table and 2 chair is rs990. If a table costs rs 30 more than a chair find the cost of each​

Answer 1

Step-by-step explanation:

Let us take the cost of a chair as 'x' and the no.of chairs are 2

So the cost of a table would be 'x+30' and the no.of tables are 5  (Given)

As per the question 2x + 5(x+30) = 990

2x + 5x + 150 = 990

7x = 990 - 150

x =  840 / 7

x = 120

So each chair costs Rs. 120 and each table costs Rs. 150
