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/
