Cow and horse are brought for rupees 2,00,000. Cow is sold at profit of 20% and horse at loss of 10%. Overall gain is 4,000 rupees. so what is the cost price of cow?

• c+h=200000..............................1
  c+20/100*c+h-10/100*h=200000+4000
  4c+3h=680000................................2
  solve 1 and 2
  c=80000

• x+y=200000---------(1)
  
  x*(20/100)-y*(10/100)=4000-----------(2)
  
  by solving 1 & 2 we can get 80000

• cp of cow+cp of horse=200000
  as overall profit is 4000 so ......sp of cow +sp of horse=204000
  by given ex. (120/100)*cp of cow=sp of cow &.........(1)
  (90/100)*cp of horse=sp of horse...................................(2)
  by adding (1)&(2) and putting cp of horse =200000-cp of cow we get
  
  cp of cow=80000.

• By method of alligation
  overall profit =(4000/200000)*100=2
  Cow - 20% profit-2% profit=18
  Horse - (-10%-2%) profit =12
  ratio of horse and cow 3:2
  so 1 cow=(2*200000)/5 =80000

• 1.2x+1.2y=240,000
  1.2x+0.9y=204000
  x=80000
