let cp of one cow is a and cp of other is b
a+b=200
sp of one cow =a*90/100....(1)
sp of another cow=a*110/100....(2)
(1)+(2)=210
solving this we get a=50 b=150

it is a very easy problem,
check by opp.
let take opp b)
sp1=150*(1+10/100) = 165

sp2 = 50*(1-10/100) = 45

now sp1 + sp2 =165 + 45 = 210 (which is equal to the given selling price).

hence original cost prices are
cp1=150
cp2=50

this is opp. based question. so do not go with lengthy process.
