Question

The cost of a chair is Rs x and the cost of a cupboard is Rs 90.If the total cost of 4 chairs and a cupboard is Rs 210, find the cost of a chair.

Answer 1

Step-by-step explanation:

cost of the chair = x rs

Cost of the cupboard= 90 rs

Total cost of 4 chairs= 4x rs

therefore, 4x+90= 210

=>4x= 210 - 90

=>4x= 120

=>x= 120/4

=>x= 30

Hence,the cost of one chair is 30 rs.

Answer 2

₹ 30

Solution :-

Cost of one chair = ₹ x

Cost of one cupboard = ₹ 90

So, the total costs of 4 chairs = ₹ 4x

A/q

4x + 90 = 210

=> 4x = 210 - 90

=> 4x = 120

=> x = 120/4

=> x = 30

Therefore, the cost of one chair = ₹ 30 .
