B purchased 15 kg apples at the rate of ₹180 per kg from a wholesaler who uses a weight of 950 grams for the kg weight. B sold all these apples at ₹180 per kg but used a weight of 750 grams for the kg weight. Find the percentage profit earned by B in the transaction (correct to 2 places of decimal).

Price of 1 kg of apples = ₹ 180

At the time of purchase 950 gm weight used instead of 1kg

At the time of sell, 750 grams weight used instead of 1kg

Total apples purchased = 15 kg

Profit percentage = $$\frac{\text{profit}}{\text{cost price}} \times 100$$​

As we know that price of the apple is constant.

B used wrong weight while purchasing and selling.

So, Percentage change is weight is profit percent for B

Now,
$$= \frac{(950-750)}{750}×100$$​

= 26.67%

Therefore, B made 26.67% profit while selling the apples
