Question

6 chairs and 7 tables can be bought for Rs2500 and 13 chairs and 11 tables can be bought for Rs 4610. Find the cost price of chair and a table.​

Answer 1

Answer:

x = 6 y = 357.14

Step-by-step explanation:

chair Price = x

table price = y

6x + 7y = 2500 (equation.............1)

13x + 11y = 4610 (equation.............2)

6x = 2500 - 7y

x = 2500 - 7y

6

x = 15000 - 42y (equation.............3)

6x + 7y = 2500

6(15000 - 42y) + 7y = 2500

90000 - 252y + 7y = 2500

-252y + 7y = 2500 - 90000

- 245y = - 87500

y = - 87500

-245

y = 357.14

x = 15000 - 42(357.14)

x = 15000 - 14994 = 6
