Q4. Find the average of the following: 1.4 kg, 2.5kg and 4.8kg
​

Answer 1

Answer:

to find average we first need to find sum of these three values=1.4+2.5+4.8

                                                                                                        =8.7

Now, to find average, we need to divide sum by total no value i.e.,3

=8.7/3=2.9  ans....

Answer 2

Average = sum-of items / no of items
=1.4+2.5+4.8/3=8.7/3=2.9kg
