Answer 1

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
