Question

A box contains 90 screws each of 100 gms and 100 bolts each of 150 gms. If the entire box weighs 35.5 kg, then the weight of the empty box is ?
A) 10.5 kgs
B) 12 kgs
C) 9.6 kgs
D) 11.5 kgs

Answer 1

90 × 100 = 9000gms = 9kg

100 × 150 = 15000gms = 15kg

9 + 15 = 24kg

35.5 - 24 => 11.5kg
