Question

One former purchased cow and its calf together cost is 9000 rs.Then after cow is selling 10% loss and calf is selling at 20% profit from the whole business neither profit nor loss,find the cost of cow

Answer 1

Answer:

cow - 6000

Calf - 3000

Step-by-step explanation:

Let price of Cow = x

Price of Calf = y

according to question

x + y = 9000 eq - i

now cow is sold at 10% loss and calf at 20% profit.

90% of x + 120% of y = 9000 ( No profit No loss)

simplify this equation

we get

9x + 12y = 90000

3x + 4y = 30000 eq - ii

solve eq. i and eq ii

we get

x= 6000

y = 3000
