Let CP of cow be x
CP of horse= 200000-x

According to formula;

SP of Cow= 100+20/100*x = 6x/5
SP of Horse= 100-10/100*(200000-x) = 1800000-9x/10

Total SP= 6x/5 + 1800000-9x/10 = 3x+1800000/10
Total CP= 200000

Gain= SP-CP
= 3x+1800000/10 - 200000
= 3x-200000

In question,given; Gain= 4000

=> 3x-200000= 4000
3x= 240000
x= 80000

let cost price of cow=x and horse price=y
x+y=2000000 -------(1)
x*20/100+y*10/100=4000
2x-y=40000 ----(2)
solving 1 n 2 :x=80000
