Answer:

Correct option is A)

Let x be the cost price of cow and y be the cost price of calf.

∴x+y=14000 .(i)

profit% on cow = 20%

∴ profit =

100

20

x

selling price of cow = cost price + profit

=x+

100

20

x

profit% on calf = 13%

∴ profit =

100

13

y

selling price of cow = cost price + profit

=y+

100

13

y

Farmer got profit on whole = 17%

∴ profit =

100

17

×14000

selling price of cow and calf = cost price of cow and calf + profit

x+

100

20

x+y+

100

13

y=14000+

100

17

×14000

∴1.2x+1.13y=16380 .(ii)

Multiplying equation (i) by 1.2. we get,

1.2x+1.2y=16800 iii)

On subtracting (iii) from (ii). we get,

1.13y−1.2y=16380−16800

∴0.07y=420

∴y=6000

On substituting y=6000 in (i). we get,

x+6000=140000

∴x=8000

∴ cost of cow = Rs. 8000

and cost of calf = Rs. 6000
