The cost price of a cow and a horse is Rs 3 lakhs. The cow is sold at 20% profit and the horse is sold at 10% loss. Overall gain is Rs 4200. What is the cost price of the cow?

• Gain=4200
  Gain=SP - CP
  4200=SP-300000
  SP=304200
  
  x+y = 300000
  1.2x+0.9y = 304200
  Solving for x = 114000

• ans=cost of cow=114000
  let cp of cow is X so cp of horse=300000-x
  now a/c to qn form d eqn-120*X/100 + (300000-X)*90/100=300000+4200
  solve u will get d same result.

• overall Gain=Rs 4200(given)
  20%is gained from selling the cow.
  so take 100%+20%=120%
  10% is the loss obtained from selling the horse.
  so 100%-10%=90%
  sp-cp=gain
  sp=cp+gain
  sp=300000+4200
  sp=304200
  to find cp of cow,assume cp of cow is x
  300000-x=cp of horse
  120x/100+90(300000-x)/100=304200
  solving above eqn we obtain the cp 0f cow as 114000

• c+h=3,00,000-> 1-eqn
  (20/100)*c - {10/100)*h =4,200 -> 2-eqn
  by solving these 2 eqns we will get rate of cow.

• Profit = 4200
  Profit =SP - CP
  4200=SP - 300000 therefore SP=304200
  x+y = 300000
  1.2x + 0.9y = 304200
  Solving for x = 114000 = CP of cow.
