Question

A milkman sold two of his buffaloes for $Rs.20,000$ each. 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

Buffalo $=Rs.20,000$

The milkman made a gain of $5\%$ while selling $1$ buffalo.

It means that if the $C.P.=Rs.100$,then

$S.P.=Rs.105$

$C.P.$ of $1$ buffalo $=2000\times \frac{100}{105}=Rs19,047.62$

Also, the second buffalo was sold at a loss of $10\%$.

It means that if the $C.P.=Rs.100$, then

$S.P.=Rs.90$

Therefore,

$C.P.$ of other buffalo $=2000\times \frac{100}{90}=Rs.22222.22$

$TotalC.P.=Rs.19047.62+Rs.22222.22=Rs.41269.84$

$TotalS.P.=Rs.20000+Rs.20000=Rs.40000$

$Loss=Rs.41269.84-Rs.40000=Rs.1269.84$

Hence, the loss of milkman is $Rs.1,\mathrm{269.84.}$

Hence, this is the answer.
