A farmer has 10 parrots and 40 horses. Find the average number of legs per animal.

Correct option is C

Given:

A farmer has 10 parrots and 40 horses.

Formula Used:

$$\text{Average number of legs per animal} = \frac{\text{Total number of legs}}{\text{Total number of animals}}$$​
Solution:
A Farmer has a total of 10 + 40 = 50 animals.
A parrot has 2 legs and a horse has 4 legs.
Total number of legs is 2 × 10 + 4 × 40 = 180
The average number of legs per animal is $$\frac{180}{50} = 3.6$$​​
