A cow & horse are brought for RS.200000.The is sold at a profit of 20% & horse at loss of 10% .If the over all gain is 4000 .Then what is cost of cow

• Using alligation:
  Cost of cow and horse come in the ratio of 2:3
  so,cost of cow is (2/5)*(2,00,000)=80,000

• let cp of cow=x
  then cp of horse=200000-x
  then sp of cow=(12/10)*x
  sp of horse=(9/10)*(200000-x)
  total sp=(12/10)*x+(9/10)*(200000-x)
  given profit=4000
  then,4000=(12/10)*x+(9/10)*(200000-x)-200000
  solving we get,x=8000
  
  cp of cow=8000

• cost of a cow=x
  horse=200000-x
  sold at 200000+4000=204000
  cow sold at 20%profit and horse sold at 10%loss
  so cow+horse selling price=6x/5+9(200000-x)/10=204000
  x=80000

• Cow + Horse = 2,00,000
  Cow--> 20% profit, Horse--> 10% loss
  let, CP of Cow= C, CP of Horse= H
  SP of Cow= 120C/100= 1.2C & SP of Horse= 90H/100= 0.9H
  C+H= 2,00,000 ------ 1
  Gain= Total SP- Total CP= (1.2C+0.9H)-(C+H)
  0.2C - 0.1H = 4000 ------- 2
  Solving 1 & 2,
  C= 80,000 & H= 36,000
