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?

1 litre

Average milk sold by milkman 1 = \(\frac{28+34+38+37+53+58+63+67 }{8}\)

= \(\frac{ 378 }{8}\)

= 47.25

Average milk sold by milkman 2 = \(\frac{ 31+32+43+41+49+59+62+69}{8}\)

= \(\frac{ 386 }{8}\)

= 48.25

Difference b/w milk sold by milkman 1 and milkman 2 = 48.25 - 47.25 = 1 litre
