a cow and a horse bought for rs. 200000. The cow is sold at a profit of 20% and the horse is sold at a loss of 10%. The overall gain is 4000. The cow price of cow is ??

• Ans : Cp of cow is 80000
  
  Let cp of cow is x & horse is y.
  so, x+y=200000 ------------------eq(1)
  now,
  (X + X * 20%) + (Y - Y * 10%) = 204000
  => 12X + 9Y=2040000 ---------------eq(2)
  After solving eq1 & eq 2 we get,
  X= 80000

• cp of cow=x
  cp of horse=200000--x
  sp of cow=6/5 x
  sp of horse=(200000-x)- (10/100)(200000-x)
  total sp=204000
  add sp of cow and sp of horse given in terms of x
  .equate with total sp
  x comes 80000
