Akash Deshwal  (11 years ago)

Ans b) 80000
x+y = 2,00,000
1.2x+0.9y = 2,04,000

solving these two equation we get x=80,000

kavitha  (11 years ago)

cow=x,horse=y
x+y=200000
120*x/100+90*y/100=204000
on solving tis we get
x=80000 y=120000

Is this solution Helpfull? Yes (28) | No (1)  

mounika  (10 years ago)

x+y=200000 ------> eqn1 [assume x=cow and y=horse]
20%x profit-10%y loss=4000
(20/100)*x-(10/100)*y=4000
2x-y=40000 --------> eqn2
by solving eqn1 and eqn2
we get x=80,000 and y=1,20,000
ans is 80,000

Gaurav Nagdev  (11 years ago)

B) 80000
20% profit on 80000= 16000/-
10% loss on 120000=12000/-
Hence total profit made=16000-12000=4000/-
Hence cost of cow = 80000/- and cost of horse=120000/-

prafull mittal  (11 years ago)

C+H=200000
therefore
c= 20%C = (120/100)C
H= -10%H= (90/100)H
so,
C+H=2,00,000+40,000=1.2C+09H ... cost price = 80,000

tejomay saha  (11 years ago)

it can be solved quickly by hit and trial method if cow prizefrom option=130000,80000,700000,120000 so the corrsponding horse cost respectively 70000,120000,130000,80000 .now applying the cnodition we get cow cost=80000

Overall profit =
4000
200000
×
100
=
2
%
4000200000×100=2%
By applying alligation rule, we get


So cost price of the cow = 2/5 x 200000 = 80,000

aditi bose  (10 years ago)

let c.p of cow be x, c.p of horse is 200000-x
s.p= {(p+100)*c.p}/100 and s.p={(100-L)*c.p)}/100
using the formula s.p for cow is 120x/100
nd for horse is {(200000-x)*90}/100
find total sp nd subtract it from total cp (given) which is the gain (4000 given) ... you will find x which is the cp of the cow. 80000

gowthami majji  (9 years ago)

cost of the cow is 80000
cost of the horse is 120000
i.e
c+h=200000
profit of the cow 20% =120000
loss of the horse 10%=90000
overall gain amount is 4000
120*c/100+90*h/100=204000

Is this solution Helpfull? Yes | No (2)  

Yadav Chevula  (9 years ago)

ans:80000
let horse cost is : h
then cost of cow=200000-h
20% profit on cow +10% loss on horse and overall profit=204000
so
(90*h)/100 + (200000-h)*(120)/100 = 204000
after solving
cost of horse = 120000
cost of cow = 80000

Is this solution Helpfull? Yes | No   

Ankita Dasgupta  (9 years ago)

THE EQUATION CAN BE WRITTEN AS
(20/100)*X-(10/100(200000-X))=4000 (LET THE PRICE OF THE COW BE X AND HORSE BE 200000-X)
X=80000
