0.0035%is your answer

Answer 2

Answer:

103.5%

Step-by-step explanation:

Let the number be x

We are given that number is increased by 15 %

New number = $x+\frac{15}{100}x = 1.15 x$

Now number is decreased by 10%

New number = $1.15 x -\frac{10}{100}(1.15x)=1.035x$

Percentage increase = $\frac{1.035 x}{x} \times 100= 103.5\%$

Hence Percentage increase is 103.5%
