C+H=200000 -(1)
1.2H+0.8C=204000-(2)
solve equation (1)&(2) ,we get H=120000
C=200000-120000=80000
ANS : B (80000)

Use alligation method here,
profit=20% loss=10%
overall profit=400*100/200000=2%

therefore by alligation
Ratio=2-(-10):20-2=12:18=2:3
price of cow= 2/5*200000= 80000 option b)

RABI KR. SHAW  (9 years ago)

profit%=(4000/200000)*100=2%
20% -10%
2%
2-(-10)=12 20-2=18
12:18=2:3
cost of cow=(2/5)*200000=80000

20 -10

2------------------------------(4000/200000)*100 [i.e 4000 in Percentage wrt 200000]

(2-(-10))=12 (20-2)=18
So,Cow:Horse=12:18
=2:3
Therefore,C.P of Cow=2/5*(200000)=80000
