ANYONE KNOW IT'S CORRECT ANSWER.......
​

Answer 1

Answer:

Rs. 10650

Step-by-step explanation:

Let the Chair as C and Tabke as t

by question 3c+t=2980 equation 1

5c+3t=2100 equation 2

now equation 1 is multiplied by 3 and substraction by equation 2

it comes 4c=6840 and price of 1 chair is 1710

Now put the value of c in equation 1 . t= 3810

Again by question cost of 4chair and 1 table

4c+t = 4×1710+3810=10650/
