Answer 2

Answer:

The price Kiran has to mark on the saree should be $4000$ rupees to get a gain of $20\%$ of the cost price after allowing $10\%$ discount.

Step-by-step explanation:

The cost price of the saree is $3000$ rupees.

It is said that Kiran wants to get a gain of $20\%$ , after allowing a discount of $10\%$ .

So we first need to check what would be the twenty percent gain, and then fix an amount whose ten percent less is the amount twenty percent gain with the cost price of the saree.

So $20\%$ of $3000$ $=3000*\frac{20}{100} =600$ rupees.

Therefore Kiran must sell the saree for $3600$ rupees to get twenty percent gain. But she want to allow ten percent discount. So price must be increased.

Let the selling price of the saree $=x$

we want $x-\frac{10x}{100} =3600$

 That is  

               $\frac{90x}{100} =3600\\\\x=3600*\frac{100}{90} =4000$

Thus the marked price of the saree should be Rs. $4000$.

ten percent of $4000=400$

Hence after allowing ten percent discount, the selling price become

$3600$ rupees.

Hence the answer.
