Buffalo gives 4 liter milk, cow gives (1/2) liter milk and goat gives 1/4 liter milk. you have to get 20 liter milk by 20 animals.what is the number of animals?

• 3 buffalos + 15 cows + 2 goats
  12 ltrs + 7.5 ltr + 0.5 ltrs

• Assume number of respective animals are x,y,z.
  x+y+z=20---(1) as the total number of animal has to be 20
  Amt of milk will be 4x+(1/2)y+(1/4)z=20---(2)
  Solving equation 1 and 2 we get
  15x+y=60 ----(3)
  
  Since buffalo gives 4litre and total milk is 20, x < 5
  But from eq 3, x cannot be more than 4;
  Further if x=1 or 2; y>20... Not possible, since total animal is 20
  Thus, x=3, y=15, z=2
  Ans: 3 buffalos, 15cows, 2goats

• @ Ganesh,
  Pls check.
  
  11 cows will give 5.5 ltr milk and not 6.5 ltrs.

• let no. of buffaloes=x
  no. of cows =y
  no. of goats =(20-x-y)
  no. of .ltrs milk given by buffalos = 4x
  no.of ltrs given by cows = y/2
  no. of litres by goat(20-x-y)/4
  total no.of ltrs of milk = 4x+(y/2)+(20-x-y)/4 =20
  
  solving the equation we get
  no. of buffalos = 3
  no. of cows =15
  no.of goats=2

• there are two possible solutions:
  1. 4 buffaloes (=16 ltrs) and 16 goats (=4 ltrs).
  2. 3 buffaloes (=12 ltrs) + 15 cows (=7.5ltrs) + 2 goats (= 0.5 ltrs)

• buffalos = 3
  cows = 15
  goat = 2

• 3 buffalos=4*3 =12 litre of milk
  15 cows=15*1/2=7.5 litres of milk
  2 goats=2*1/4=.5 litres of milk
  
  s0 20 animals and 20 litres of milk

• 3 buffaloes * 4 liter milk = 12 liters
  15 cows * 1/2 liter milk = 7.5 liters
  2 goats * 1/4 liter milk = 0.5 liters
