10.5 will be your answer, the radius will always be midway of the total so therefore 21 divided by 2 which would make it half would be 10.5 for the radius.

3. A dealer altered his trade discount from 15% to 10%. By whatpercent was selling price altered?
BabaBlast [244]

Answer:

Regular selling price (price before discount) 100%.

Price after trade discount of 15% is 85% of regular selling price..

Price after trade discount reduced to 10% is 90% of regular selling price.

By reducing the trade discount from 15% to 10% meant increasing the selling price by 5% of the selling price before applying the trade discount.
