Question

4 Chairs And 2 Tables =1700 And 5 Chairs And 2 Tables =1800 Find Cost Of Chair And Table

Answer 1

Let cost of 1 chair be Rs. x

cost of be table be Rs. y

According to the question,

cost of 4 chairs and 2 tables is Rs. 1700

So, 4x + 2y = 1700 ……...... (i)

Also,

cost of 5 chairs and 2 tables is Rs.1800

So 5x + 2y = 1800 ……….. (ii)

from equation (i) and (ii)

4x + 2y = 1700

5x + 2y = 1800

-----------------------

x = 100

putting the value of x in equation (ii), we get

5x + 2y = 1800

5(100) + 2y = 1800

500 + 2y = 1800

2y = 1300

y = 650

Hence, cost of each chair,x = Rs. 100

cost of each table,y = Rs. 650

Hope this helps!

Answer 2

Answer:

Step-by-step explanation:let chairs =c

Let tables =t

4c+2t= 1700

5c+2t=1800

Subtracting both equations we get

-c+0=-100

That implies

Cost of each chair =100

For finding cost of table put c in one of the equations

5*100+ 2*t= 1800

2t= 1300

T=650
