number of animal feet:
50*2 = 100
45 *4 = 180
8 * 4 = 32
total animal feet : 312, total feet = 312 +2x

number of animal heads:
50+45+8 = 103, total head = 103 + x

(312 + 2x) - (103 + x) = 224
x = 15

so there're 15 keepers
(note: assume that all hen have 2 feet, all goat have 4 feet, all camel have 4 feet and the keepers are human that have 2 feet)
