The average weight of 20 boxes of oranges is 2 kg, and the average weight of 30 boxes of mangoes is 3 kg. Find the average weight of these boxes of fruits, taken together.
Answer & explanation
Correct answer: option 1
Sum of weight of 20 boxes of oranges = 20 × 2 = 40 kg
Sum of weight of 30 boxes of mangoes = 30 × 3 = 90 kg
Average weight of boxes of both fruits together = \(\frac{90 + 40 }{50}\)
= \(\frac{130}{50}\) = 2.6 kg
