    Let the weight of new parcel = $$x$$ kg Average weight of 10 parcels = 1.7 kg => Total weight of 10 parcels = $$1.7 imes 10=17$$ kg After adding the new parcel, average weight = $$1.7-0.06=1.64$$ kg => $$frac{17+x}{11}=1.64$$ => $$17+x=1.64 imes 11=18.04$$ => $$x=18.04-17=1.04$$ kg => Ans - (A)
