Let the number of tables be x and weight of chair be y.

so, x.9y = 1200
xy = 1200/9

total weight of chairs = 6xy = 1200×6/9 = 800

Total weight of chair and table = 1200 +800 = 2000kg

Given total weight of tables:
9xy = 1200kg
xy =  \frac{1200}{9}

Total weight of chairs :
6xy =  \frac{1200}{9}  x6
=800kg

Combined weight of tables and chairs:
= 800+1200 = 2000kg
 Hence, C
