The average weight of five cartons is 44.4 kg. If a sixth carton is included, the average weight decreases by 1 kg. What is the weight of the sixth carton? Correct Answer 38.4 kg

Average weight of five cartons = 44.4 kg

⇒ Total weight of five cartons = 44.4 × 5 = 222 kg

Now,

⇒ Average weight of six cartons = 44.4 – 1 = 43.4 kg

⇒ Total weight of six cartons = 43.4 × 6 = 260.4 kg

⇒ Weight of sixth carton = 260.4 – 222 = 38.4 kg
