The average weight of 263 fertilizer bags is 63 kg. If the weight of the box(in which the fertilizer bags are kept) is included, the calculated average weight per fertilizer bag will increase by 0.8 kg. What is the weight of the box? (In kg)

Correct option is C

Average weight of 263 bags = 63 kg

Total weight of bags
= 263 × 63
= 16569 kg

New average increase = 0.8 kg

Increase in total weight
= 263 × 0.8
= 210.4 kg

This increase is due to the weight of the box.
Weight of box = 210.4 kg
