Farmer Jones sold a pair of cows for Rs. 210 , On one he made a profit of ten percent and on the other he lost ten percent. Altogether he made a profit of five percent. How many did each cow originally cost him?

• suppose cost is x and y rs.
  (x*110/100)+(y*90/100)=210;-----eq(1)
  c.p of (x+y)=(s.p.*100)/(100+gain)=200
  so x+y=200---------eq(2)
  solving both eq
  x=150
  y=50

• 150,50.
  cost of 1st cow is 150,if he sells at 10% profit then the selling price is 165.
  cost of 2nd cow is 50,if he sells at 10% loss then the selling price is 45.
  so total cost earned after selling pair of cows is 210.
