In a group of ducks and cows, the total number of legs are 24 more than twice the no. of heads. Find the total no.of buffaloes. Pick one:  A) 10  B) 12  C) 14  D) 16  E) 17
Let the number of buffaloes be x and the number of ducks be y   =&gt; 4x + 2y = 2 (x + y) + 24   =&gt; 2x = 24 =&gt; x = 12   12
