to double the profit from the present 10 % the present selling price of rs.100 will have to be increased approximately to

110

To double the profit from the present 10%, we need to first calculate the current profit.

Profit is calculated as a percentage of the selling price. If the profit is 10%, then it means that the profit is 10% of the selling price.

Profit = 10% of Selling Price

Since the selling price is Rs. 100, we can calculate the profit as follows:

Profit = 10% of Rs. 100
= Rs. (10/100) * 100
= Rs. 10

Now, to double the profit, we need to determine the new selling price that will result in a profit of Rs. 20 (double of Rs. 10).

Let's assume the new selling price is 'x'. The profit calculation would be as follows:

Profit = 10% of New Selling Price

Therefore,

Rs. 20 = 10% of x

To find the value of 'x', we need to isolate it on one side of the equation:

x = (20 / 10%)

To calculate the value of 'x', divide Rs. 20 by 10% (which is equivalent to 0.1 as a decimal):

x = Rs. 20 / 0.1
= Rs. 200

So, to double the profit from the present 10%, the present selling price of Rs. 100 will have to be increased approximately to Rs. 200.
