Answer 1

Answer:

CP of first cow =550 ; CP of 2nd cow =750

Step-by-step explanation:

Let,

CP1 and SP1 for 1st  cow

CP2 and SP2 for 2nd cow

Given,

each cow was sold for the same price

SP1=SP2

Let CP1=x

      CP2=(1300-x)

We know that SP=((100+gain)/100)*CP

SP1=(100+gain)/100*x

SP2=(100-loss)/100*(1300-x)

(120/100)*x=(88/100)*(1300-x)

120x=1300*88-88x

208x=1300*88

x=550     (CP1)

1300-550=750    (CP2)
