On one he made a gain of 5% and on the other a loss of
10%. Find his overall gain or loss. (Hint: Find
CP of each)​

Answer 1

gain =1000 rupees, loss =2000 rupees

Answer 2

Answer:

In overall transaction it is loss for milkman

Step-by-step explanation:

lets name those buffaloes as b1 and b2

a milkman sold his buffaloes for RS 20000 each

one gain is 5%

and loss is 10%

c.p of b1

X+5/100 multiplied by X =20000

take a LCM

100x+5x/100=20000

105x/100=20000

X=20000 divided by 105/100

c.p of b1 is RS 19047.619

c.p of b2

variable is y

y-10/100y=20000

take LCM

100y-10y/100 =20000

90y/100=20000

y=20000 divided by 90/100

y = 22222.22

c.p of b2 = 22222.22

total c.p of b1 + b2

19047.619+22222.22=41269.839

loss =c.p-s.p

41269.839-40000=1269.839

so th answer is loss for milkman
