A doll is solid for RS 220 What was the cost of doll if rate of profit was 10% of cost?

Explanation

To find the cost of the doll when it is sold for Rs. 220 with a profit rate of 10%, we can use the following formula:

Selling Price=Cost Price+Profit

Given that the profit is 10% of the cost price, we can express the profit as:

Profit=0.10×Cost Price

Let the cost price be C. Therefore, the selling price can be expressed as:

Selling Price=C+0.10C=1.10C

We know the selling price is Rs. 220, so we can set up the equation:

1.10C=220

Now, we can solve for C:

C=2201.10=200

Thus, the cost of the doll was Rs. 200.
