Question

the cost of two tables and five chairs is Rs2300 . if a table costs rs 30 more than a chair, find the price of each​

Answer 1

Answer:

let cost of chair be rs x and cost of table be x+30 then,

2( x+30)+ 5x

2x+60+5x= 7x+60

but, cost of two tables and 5chairs is 2300.(given)

7x + 60 = 2300

7x= 2300-60

7x = 2240

x= 2240/7 = 320

hence cost of chai r = rs320

and cost of table = 320+30 = 350

Answer 2

Question:

The cost of two tables and five chairs is Rs.2300. If a table costs Rs.30 more than a chair, find the price of each.

Answer:

Let the cost of the chair be x

∴ cost of the table = (30+x)

ATQ,

(30+x) + (30+x) + x + x + x + x + x = 2300

$\implies$ 30 + 30 + x + x + x + x + x + x + x = 2300

$\implies$ 60 + 7x = 2300

$\implies$ 7x = 2300 - 60 = 2240

∴ x = 2240/7

     = 320

∴ Cost of a chair = x = Rs. 320

Cost of the table = (30+x) = (30+320) = Rs. 350

∴ Ans. = Chair - Rs. 320

              Table - Rs. 350
