a man buys two cows for 1350 and sells one so as to lose 6% and the other so as to gain 7.5% and on the whole he neither gains nor loss.what does the first cow cost?

Read Solution (Total 4)

two cow purchase in x & y rs. so... x+y = 1350
1st sell with 6% loss means .94x rs
2nd sold with 7.5% profit means 1.075y rs = 1.075(1350-x)
no loss no gain means cost price = selling price
.94x + 1.075(1350-x) = 1350
x= 750 rs
first cow purchased in 750 Rs.

x+y =1350
0.94*x + 1.075y = 1350
x+y=.94x+1.075y
.06x=.075y
y=(0.06/0.075)x
so putting it in 1st eqn
x+(6/7.5)x=1350
x=750 rs

(1350*7.5)/(7.5+6)=750 rs(first cow)

let cost of cows are x & 1350-x
then
.94x+1.075(1350-x)=1350
as no profit no loss so cp=sp
it gives x=750 ans
