Question 62

The Table presents the amount of milk (in litres) sold by two milkmen in eight days.

What is the difference between the average milk sold per day by Milkman 1 and the average milk sold by Milkman 2 per day?

Solution

average milk sold per day by Milkman 1 = $$\frac{28+34+38+37+53+58+63+67}{8}$$

= $$\frac{378}{8}$$

= 47.25

average milk sold per day by Milkman 2 = $$\frac{31+32+43+41+49+59+62+69}{8}$$

= $$\frac{386}{8}$$

= 48.25

Difference between the average milk sold per day by Milkman 1 and the average milk sold by Milkman 2 per day = 48.25-47.25

= 1
