Answer 2

Given:

Ashish studies for 3 hours ,6 hours,4hours,2 hours,1 hour ,7/3 hours ,1/2 hours in a week

To Find:

How many hours does he studies daily on average ?

Solution:

Ashish studies for hours in a week :

Day 1 = 3 hours

Day 2 = 6 hours

Day 3 = 4 hours

Day 4 = 2 hours

Day 5 = 1 hour

Day 6 = $\frac{7}{3}$hours

Day 7 =$\frac{1}{2}$hours

$Average = \frac{\text{Sum of all observations}}{\text{No. of observations}}\\Average = \frac{3+6+4+2+1+\frac{7}{3}+\frac{1}{2}}{7}$

Average = 2.69

Hence He studies daily on 2.69 hours on average
