Q:

In a group of buffaloes and ducks the number of legs are 24 more than twice the number of heads. What is the number of buffaloes in the group ? 

A) 6 B) 18
C) 12 D) 24
 
Answer & Explanation Answer: C) 12

Explanation:

Let the number of buffaloes be x

 and number of ducks be y.

Now, number of heads = x+y

Number of legs = 4x+2y  .......(1) 

But given that legs = 2(x+y)+24 ......(2)

 

solving (1) & (2),we get

 

4x+2y=2x+2y+24 

 

--> x=12.

 

Therefore number of buffaloes =12
