The Bar graph given below presents the amount (volume in litres) of water in ten different mixtures.
What is the average amount of water per mixture?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 23.6 litre.
Average = Sum of numbers/Total numbers
From the bar graph:
Average amount of water per mixture = 23.6 litre
⇒ (12 + 14 + 15 + 17 + 21 + 24 + 28 + 31 + 34 + 40)/10
⇒ 236/10 = 23.6
