Answer 2

Answer:

The net gain earned by him is 71.43%.

Step-by-step explanation:

Given : A man says he sells a corn at a profit of 20% and uses weights that are 30% less than actual.

To find : The net gain earned by him?

Solution :

Let a man sells 1 g corn at Rs.1

Let he sells 1000 g corn at Rs.1000.

He sells a corn at a profit of 20%

i.e. Profit = 1000+20=Rs.1200

He uses weights that are 30% less than actual.

i.e. $1000-30=700$

So, Actually he sells 700g of corn at Rs.1200

Cost price = Rs.700

Selling price = Rs.1200

Profit percentage is given by,

$P\%=\frac{SP-CP}{CP}\times 100$

$P\%=\frac{1200-700}{700}\times 100$

$P\%=\frac{500}{700}\times 100$

$P\%=71.43\%$

Therefore, The net gain earned by him is 71.43%.
