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 in the caravan, the number of keepers is

A. 5 B. 8
C. 10 D. 15

• let the no.of keepers be x
  total no.of feets=2*50+4*45+8*2+x*2=2x+312
  total no.of heads=50+45+8+x=103+x
  so 2x+312=103+x+224
  x=15

• Let the no. Of keepers be x
  Then total no of feet is = 2×50 + 4×45 + 8×4 + x×2 = 2x + 312
  Total no of heads = 50+45+8+x
  According to qs. 2x +312 = 103+x+ 224;
  X=15

• calculate feet-head of each one
  hens=keepers=2-1=1
  goats=camels=4-1=3
  50*1+45*3+8*3+x*1=224
  x=15
