♠️How??

$\implies\sf$Buffalo = Rs 20000

$\implies\sf$The milkman gain of 5% for selling one buffalo

$\implies\sf$That means if C.P = Rs 100

S.P = 105.

C.P. of one buffalo = $\bf\frac{2000 * 100}{105}$

$\implies\sf$ Rs 19,047.62

Second buffalo was sold at a loss of 10%.

If C.P = 100, then S.P = 90.

C.P. of other buffalo = $\bf\frac{2000 * 100}{90}$

$\implies\sf$Rs 22222.22

Total C.P. = Rs 19047.62 + Rs 22222.22

$\implies\sf$Rs 41269.84

Total S.P. = Rs 20000 + Rs 20000

$\implies\sf$Rs 40000

Loss = Rs 41269.84 − Rs 40000

$\implies\sf$Rs1269.84
