In a caravan, in addition to 50 hens there are 45 goats and 8 camels with some keepers. If the total number of feet be 224 more than the number of heads, find the number of keepers.  Choose the correct choice from the following choices.
A) 11  B) 12  C) 13  D) 14  E) 15
Let the number of keepers be x.   Then, total number of feet = 2*50+4*45+4*8+2x   = 2x + 312   Total number of heads = 50+45+8+x = 103 + x   Now, (2x+312) = (103+x)+224   =&gt; x = 15   ANSW15R:15
