17. 

    Hence C.

18. 

    Hence C.

19. 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.

20. Let radius be 100 sot that area is p r² = 10,000 p

    New radius will be 120.

    New area is p r² = p ´ 120 ´ 130, i.e. 14400 p

    \ Increase in area = 4400 p

    

    Hence A.
