Question

a milkman sold two of his buffaloes for 20000 each on one he made a gain of 5% and on the other a loss of 10% find his overall gain or loss find CP office

Answer 1

Let the two buffaloes be  a and b

Let the CP of A=x

Given that,

Profit=5% of x

        =5/100 * x

        =x/20

SP = CP+Profit

20000 = x+x/20

20000 = 21x/20

20000*20/21=x

Let the CP of B = y

Given that,

Loss = 10% of y

        = 10/100*y

        =y/10

But,

SP = CP-Loss

20000=y-y/10

20000=9y/10

20000*10/9=y

Profit = 5% of x

         = 5/100*400000/21

         =20000/21

         =952.38

Loss= 10% of y

       = 10/100*20000/9

       = 20000

Loss>Profit

Loss = Loss-Profit

       =2222.22-952.38

       =Rs.1269.84
