At a courier shop, the weights of 8 parcels were found to be 1.5 kg, 1.25 kg, 1.35 kg, 750 gm, 950 gm, 0.7 kg, 0.4 kg, and 0.5 kg. Find their average weight.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 925 gm.
We know that,
Average = Sum of observations/Total number of observations
Now,
First, we will convert the gram weights into kilogram weights;
Sum of the weights of 8 parcel = (1.5 + 1.25 + 1.35 + .75 + .95 + 0.7 + 0.4 + 0.5) kg = 7.4 kg
Required average = 7.4/8 = 0.925 kg or 925 gm
