Question

A milkman sold two of his buffaloes for Rs. 40,000 each. On one he gained 5% and on the other, he lost 10%. Find his gain or loss in the whole transaction.

Answer 1

Answer:

loss=2180.28

Step-by-step explanation:

For first buffalo

let the cp be x

we know, profit%=profit/cp *100

5=40000-x/x*100

5x/100=40000-x

106x/100=40000

106x=40,00,000

x=37735.84

For second buffalo,

let the cp be y

we know, loss%=loss/cp*100

10=y-40000/y*100

10y/100=y-40000

90y=4000000

y=44444.44

So total cost price

cp=37735.84+44444.44

cp=82180.28

now, as cp>sp so there is loss

loss=cp-sp

=82180.28-80000

=2180.28
