Answer 2

The gain percentage is 28.33%.

Step-by-step explanation:

Given : By selling an article for Rs.600 A gained 10% .

To find : His gain percentage if he sells it for Rs.700 ?

Solution :

The selling price is Rs.600.

Gain% = 10%

The cost price is given by,

$CP=\frac{100}{100+G\%}\times SP$

$CP=\frac{100}{100+10}\times 600$

$CP=\frac{100}{110}\times 600$

$CP=545.45$

Now, The selling price is Rs.700.

The profit% is given by,

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

$P\%=\frac{700-545.45}{545.45}\times 100$

$P\%=\frac{154.55}{545.45}\times 100$

$P\%=28.33\%$

Therefore, the gain percentage is 28.33%.
