Question

The cost of a chair and table is 296 .If the cost of table is 20 more than the chair find the cost of chair​

Answer 1

Step-by-step explanation:

Let the cost of 1 chair be x

cost of 1 table be y

As per the problem,

x + y = 296 …………(i)

and x = 20 + y …………(ii)

Now putting eq (ii) in eq (I)

(20 + y) + y = 296

20 + 2y = 296

2y = 296 -20

y = 276/2

y = 138

•: the cost of 1 table = 138 Rs.

now, from (ii)

x = y + 20

x = 138 + 20

x = 158 Rs.
