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 xx+
100
15
x=1.15x
Now number is decreased by 10%
New number = 1.15 x -\frac{10}{100}(1.15x)=1.035x1.15x−
100
10
(1.15x)=1.035x
Percentage increase = \frac{1.035 x}{x} \times 100= 103.5\%
x
1.035x
×100=103.5%
Hence Percentage increase is 103.5%
