Answer 1

Answer:

1) c.p=20x18=360

2) c.p=25x16=400

Totalc.p. = 760

Sp=19x45=855

Gain=855-760=Rs 95

%Gain=95 / 760 x 100 = 12.5%

Answer 2

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

$20\times 18+25\times 16\\\\=360+400\\\\=Rs.\ 760$

Selling price of total quantity of rice = Rs. 19

So, Total selling price would be

$19\times (20+25)\\\\=19\times 145\\\\=Rs.\ 855$

So, Profit % would be

$\dfrac{855-760}{760}\times 100\\\\=\dfrac{95}{760}\times 100\\\\=12.5\%$

Hence, his gain percent is 12.5% in whole transaction.
