Hence C.

Weight of 90 nuts at 100 gms each is 90 ´ 100 ro 9000 gms., i.e. 9 kg.
Similarly weight of 100 bolts of 150 gms each is 15000 gms or 15 kg.
Hence weight of nuts and bolts is 15 + 9 = 24 kg.
Hence weight of empty box is 25.5  24 = 115.5 kg
Hence D.

Let radius be 100 sot that area is p r^{2} = 10,000 p
New radius will be 120.
New area is p r^{2} = p ´ 120 ´ 130, i.e. 14400 p
\ Increase in area = 4400 p
Hence A.
