Correct Answer: 2.6 kg
Solution : Average weight = $\frac{\text{Sum of values}}{\text{Total values}}$ Total weight of oranges = 20 × 2 = 40 Total weight of Mango = 30 × 3 = 90 Total number of boxes = 30 + 20 = 50 Average weight = $\frac{90 + 40}{50}$ ⇒ Average weight = $\frac{130}{50}$ = 2.6 kg Hence, the correct answer is 2.6 kg.
