In a group of ducks and cows, the total number of legs are 24 more than twice the number of heads. Find the total number of cows.  Choose the correct choice from the following choices.
A) 12 B) 14 C) 16 D) 18 E) 20
Let the number of ducks be d   and number of cows be c   Then, total number of legs = 2d + 4c = 2(d + 2c)   total number of heads = c + d   Given that total number of legs are 24 more than twice the number of heads   =&gt; 2(d + 2c) = 24+ 2(c + d)   =&gt; d + 2c = 12 + c + d   =&gt; 2c = 12 + c   =&gt; c = 12   i.e., total number of cows = 12   12nswer is 12.
