Question

If the cost of 5 tables exceeds the cost of eight chairs by Rs.150. Write a linear equation in two variables. Also find the cost of one table if cost of one chair is Rs.240.

Answer 1

Hey mate!

Here's your answer!!
----------------------------
Let the cost of 1 table be x and the cost of 1 chair be y.

Cost of 5 tables = 5x
Cost of 8 chairs = 8y

8y + 150 = 5x

1 chair costs rs 240

(8 × 240) + 150 = 5x

1920 + 150 = 5x

5x = 2070

x = 2070/5

x = 414.

Answer 2

Answer:

Let the cost of 1 table  =Rs $x$

Let the cost of 1 chair = Rs $y$

cost of 5 tables = Rs 5$x$

cost of 8 chairs = Rs 8$y$

According to question,

5 $x$− 8$y$ = 150  

Put $y$  = 240, we get

5$x$ − 8 × 240  = 150

⇒5$x$= 150 + 1920 = 2070

⇒ $x$= 414

So, cost of 1 table  = Rs 414
