My neighbor has both chickens and roosters. He has a total of 31 bords. The number of chickens is ten more than twice the number of roosters. How mant chickens does he have

Answer :

Answer:

the neighbor has in total 24 chickens.

Step-by-step explanation:

Total number of animals   =  31

Let the number of roosters  = k

Then , the number of chickens he has  = 2 k + 10

Now, according to the question:

(k)  + ( 2k + 10)  = 31

or, 3k = 31 -10  

⇒ 3k = 21, or  k = 21/3

⇒ k = 7

Hence, the number of roosters he has = k = 7

And the number of chicken he has  2k +  10.

= (2 x 7)  +  10

= 24

Hence, the neighbor has total 24 chickens.
