31 hens are there in the farm in which the farmer counted.
Given:
Total number of legs = 78
Total number of heads = 35
To find:
Number of hens = ?
Solution:
Total number of legs the farmer counted = 78.
And there are 35 heads that consist of both cows and hens.
We have to calculate the number of hens.
We can solve this by forming an algebraic expression
According to the question,
Let the number of cows = a
Let the number of hens = b,
Therefore, 4a + 2b = 78 ---(1) and
a + b = 35 ---(2)
solving (1) and (2), we get,
a = no. of cows = 4 and b = no. of hens = 31.
Therefore, there are 31 hens in total.
