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 most appropriate option
A) 25 B) 20 C) 15 D) 13 E) 14
Let the number of keepers be x then,   Total number of heads =(50 + 45 + 8 + x)= (103 + x).   Total number of feet = (45 + 8) x 4 + (50 + x) x 2 =(312 +2x).   (312 + 2x)-(103 + x) =224 ==&gt; x =15.   Hence, number of keepers =15.   Answer 15.
