Answer 1

Answer:

Given,

Average weight of 45 sacks = 36 kg

Therefore, total weight of 45 sacks = 36 × 45 kg

= 1620 kg

if 1 new sack is added then the average weight of 46 sacks became (36 + 2) = 38 kg

Therefore, the total weight of 46 sacks = 46 × 38 kg

= 1748 kg

Answer :- The weight of sack kept later in the truck is (1748 - 1620) = 128 kg
