Question

Solve any two of the following. 

In some families in a colony the daily purchase of milk in litre is 1, 3, 2, 2, 4, 1, 2, 2, 1. Find the mean, median and mode of daily purchase of milk. 

Answer 1

mean=`(1+3+2+2+4+1+2+2+1)/9=18/9=2` 

Acending order is 1, 1, 1, 2, 2, 2, 2, 3, 4
The number at middle place is 2.

∴ Median = 2
The number repeated maximum number of times is 2.
∴ the mode is 2
