To find the number of apples that were sold as fresh fruit, we need to subtract the number of discarded apples from the total number of apples picked.
Total number of apples picked = 200
Number of apples discarded = (1/10) * 200 = 20
Number of apples sold as fresh fruit = Total number of apples picked - Number of apples discarded
= 200 - 20
= 180
Therefore, 180 apples were sold as fresh fruit.

To find the total area of the town of Oak Manor, we will use the formula for the area of a rectangle, which is length multiplied by width.
Length = 3.8 miles
Width = 4.2 miles
Total area = Length × Width
= 3.8 miles × 4.2 miles
= 15.96 mi²
Therefore, the total area of the town of Oak Manor is 15.96 square miles.

To find the height of the basketball player's son, we need to multiply the height of the basketball player by the fraction representing the son's height compared to his father's height.
Basketball player's height = 6/23 ft
Son's height compared to basketball player's height = 1/4
Son's height = Basketball player's height × (Son's height compared to basketball player's height)
= (6/23) ft × (1/4)
= 6/92 ft
Therefore, the son is (6/92) feet tall, which can be simplified to 1 2/3 ft or 1 and 2/3 ft.
