let the cost prize of cow and horse be x and y.
therefore x + y = 400000 eqn(1)
20% profit for cow so 120/100=1.2x and 10% loss for horse so 90/100=0.9y
therefore 1.2x + 0.9y = 404200 eqn(2)
solve (1) and (2)
x=114000

say cost price of cow=x, cost price of horse =300000-x
3 lakhs-(120x/100+90(3 lakhs-x)/100)=4200
then x=86000(ans)

x+y=300000..............................(i)
(x+0.2x+0.9+y-0.1y)-300000=4200..........(ii)
solve this and you will get x=114000 (cows price)

c+h=300000
1.2c+0.9h=304200
by solving them we get

c+h=300000 ------>1
1.2c+0.9h=304200 ------->2

solving 1 & 2 we get c=114000
