Question

the total cost of 5 tables and 4 chair is rupees 1560 if a table cost of rupees 60 more than the cost of a chair find the cost of one table and one chair​

Answer 1

Step-by-step explanation:

Let the cost of a chair be, x rs

then, cost of a table =( x + 60 ) rs

cost of 4 chairs = 4x rs

cost of 5 tables = 5(x +60) rs

then , 4x + 5(x+60) = 1560

4x + 5x + 300 = 1560

9x + 300 = 1560

9x = 1560 - 300 = 1260

x= 1260/9 = 140

therefore, cost of 1 chair= 140 Rs

cost of 1 table = (140 + 60) = 200 Rs

Hope this answer helps you... :)

Answer 2

Answer

cost of 1 chair 140 rs

cost of 1 Table 200 rs

Step-by-step explanation:

Let T be tables

Let C be chairs

5T + 4C = 1560 rs

A Table cost is 60 more than a chair

T = C + 60

Hence 5 ( C + 60) + 4C = 1560

5C + 300 + 4C = 1560

9C + 300 = 1560

9C = 1560 - 300

9C = 1260

C = 1260/9

C = 140

Hence cost of 1 chair is 140 rs

And cost of 1 table = C + 60

= 140 + 60

= 200 rs
