Question

grocer purchased 200 kg of rice at Rs. 25 per kg. He sold 80 kg of it at a gain of 10% and 40 kg at a loss of 4%.  find his loss and gain percentage in whole transaction​

Answer 1

$\huge \color{purple}{ \colorbox{black}{answer}}$

Purchase cost =200×25=Rs5,000

Selling price of 80 kg rice - at 10% gain ⇒ 110% of price

$\large \frac{110}{100} \times rs \: 25$

So money earned by selling 80 kg rice =

$\large \frac{110}{100} \times 25 \: \: \: rs2200$

Selling price of 40 kg rice at a loss of 4% ⇒ 96% of price

$\large \frac{96}{100} \times rs25$

Money earned by selling 40 kg

$40 \times \frac{96}{100} \times 25 \: \: \: \: \: rs960$

Remaining quantity =200−40−80=80kg

Total gain required = 8% ⇒

Overall money to be earned thru sales =

$\frac{108}{100} \times cost =$

$\frac{108}{100} \times 5500 \: \: \: \: \: rs \: 5400$

Money to be earned through sale of remaining 80 kg

=Rs5,400−Rs2,200−Rs960=Rs2,240

Selling price of the remainder rice =

$\frac{rs \: 2240}{80 \: kg} = rs \: 28kg$
