Question

The cost of 1 table and 4 chairs rs3,400.if a tables costs rs900more than a chair ,find the cost of a chair and a table

Answer 1

Step-by-step explanation:

let cost of chair be X .

then cost of table= X+900

(X+900)+ 4X= 3400

5X= 3400-900

5X= 2500

X= 500

therefore, cost of each chair is Rs 500 and cost of each table is Rs( 500+900)= Rs 1400

Answer 2

Let :-

The cost of chair be x

The cost of table be x + 900

Here :-

4x + x + 900 = 3400

= 5x + 900 = 3400

= 5x + 900 - 900 = 3400 - 900

= 5x = 2500

= x = 2500/5

= x = 500

So :-

The cost of a chair = ₹500

The cost of a table = ₹500 + ₹900 = ₹1400
