Answer:
His gain percent is 12.5% in whole transaction.
Step-by-step explanation:
Since we have given that
Quantity of rice = 20 kg
Price per kg = Rs. 18
Quantity of rice = 25 kg
Price per kg = Rs. 16
So, Total cost would be
\begin{gathered}20\times 18+25\times 16\\\\=360+400\\\\=Rs.\ 760\end{gathered}
20×18+25×16
=360+400
=Rs. 760
Selling price of total quantity of rice = Rs. 19
So, Total selling price would be
\begin{gathered}19\times (20+25)\\\\=19\times 145\\\\=Rs.\ 855\end{gathered}
19×(20+25)
=19×145
=Rs. 855
So, Profit % would be
\begin{gathered}\dfrac{855-760}{760}\times 100\\\\=\dfrac{95}{760}\times 100\\\\=12.5\%\end{gathered}
760
855−760
×100
=
760
95
×100
=12.5%
Hence, his gain percent is 12.5% in whole transaction
