The daily sale of milk (in litres) in a ration shop for eight days is as follows\( \mathbf{6 0}, \mathbf{4 0}, \mathbf{1 0}, \mathbf{4 0}, \mathbf{4}, \mathbf{7 0}, \mathbf{3 0} \) and \( \mathbf{1 0} . \) The average daily sale is-
- A. 40
- B. 33
- C. 64 \)
- D. 24
Step-by-step solution
Sum of daily sales = 60 + 40 + 10 + 40 + 4 + 70 + 30 + 10 = 264 litres. Number of days = 8. Average = 264 / 8 = 33 litres.
