Find the result when 20 is increased by 95%.

Answers

10 percent is 2 and 5 percent is 1. 2 times 9 is 18. That is 90 percent. 18 plus 1 is 19 which is 95 percent. 20 plus 19 is 39 so the answer is 39.

Final answer:

To find the result when 20 is increased by 95%, you will need to calculate 95% of 20, which is 19, and then add it to 20. The result is 39.

Explanation:

To find the result when 20 is increased by 95%, you will need to calculate 95% of 20 and add it to 20. Here's how:

  1. Calculate 95% of 20: 0.95 * 20 = 19
  2. Add 19 to 20: 20 + 19 = 39

So, the result when 20 is increased by 95% is 39.
