Question

A person has some chickens and goats. if the number of heads is 48 and the number of the feet is 140, then how many chickens are​

Answer 1

Answer:

26 chickens and 22 goats.

Step-by-step explanation:

let the number of chickens be x and the number of goats is equal to y.

total number of heads = 48

x+y=48.

x = 48-y. ......eqn.1

total number of feet =140

2x +4y = 140

2(48-y) + 4y = 140 ...from ( eqn.1)

96-2y +4y = 140

2y= 140-96

2y = 44

y = 22

substituting the value of y in equation 1,we get

x=26

therefore, the number of chickens =x=26.
