a cow and a horse are brought for 200000. the cow is sold at a profit of 20% and the horse at a loss of 10%. the overall gain is 4000. the cost price of cow is
a)130000
b)80000
c)70000
d)120000
e)none of these

• calculate with option.
  
  if price of cow is=80000,
  price of horse is=120000.
  
  gain of 20% on cow,
  =16000.
  loss of 10% on horse,
  =12000.
  
  total profit=(16000-12000)=4000.
  
  ans is b.

• C*120/100 + H*90/100 = 204000........i)
  
  C+H = 200000.........ii)
  
  C= 800000
  
  ans- b) 800000

• C+H=200000 -(1)
  1.2H+0.8C=204000-(2)
  solve equation (1)&(2) ,we get H=120000
  C=200000-120000=80000
  ANS : B (80000)

• Use alligation method here,
  profit=20% loss=10%
  overall profit=400*100/200000=2%
  
  therefore by alligation
  Ratio=2-(-10):20-2=12:18=2:3
  price of cow= 2/5*200000= 80000 option b)

• profit%=(4000/200000)*100=2%
  20% -10%
  2%
  2-(-10)=12 20-2=18
  12:18=2:3
  cost of cow=(2/5)*200000=80000

• 20 -10
  
  2------------------------------(4000/200000)*100 [i.e 4000 in Percentage wrt 200000]
  
  (2-(-10))=12 (20-2)=18
  So,Cow:Horse=12:18
  =2:3
  Therefore,C.P of Cow=2/5*(200000)=80000
