A farmer has 10 Parrots and 40 horses. Find the average number of legs per animal.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 3.6.
We know that,
Average = Sum of observations/Number of observations
Now, according to the question
The farmer has a total of animals = 10 + 40 = 50
A parrot has 2 legs and a horse has 4 legs
The total number of legs = (2 × 10) + (4 × 40) = 180
The average number of legs per animal = 180/50 = 3.6
