Total number of fruits sold in a year = 10000
⇒ Number of Watermelons sold in a year = 10000 × 17/100 = 1700
⇒ Number of Oranges sold in a year = 100000 × 10/100 = 1000
⇒ Number of Apples sold in a year = 10000 × 21/100 = 2100
∴ The average number of orange, watermelon and apples sold in a year = (1700 + 1000 + 2100)/3 = 4800/3 = 1600
