Question

The ratio of the chickens to pigs to horses on a farm can be expressed as the triple ratio 20:4: 6 if there are 120 chickens on the farm, then the number of horses on the farm is

Answer 1

The number of horses is 36

Given:

Ratio of chickens: pigs: horses = 20 : 4 : 6

To find:

Number of horses on the farm

Solution:

By multiplying them with a constant $x$

Number of chickens $= 20x$

Number of pigs $= 4x$

and, Number of horses $= 6x$

But, given that,

Number of chickens = 120

Therefore

20x = 120

or, $x=\frac{120}{20}=6$

Hence, number of horses in a farm $= 6x = 6 \times 6 = 36$
