Let the original price of the share be x
When the share rose by 10%, the share's value became
x + x(10/100)
= x + 0.1x
= 1.1x
When the share fell by 10%, the share's new value became
1.1x - 1.1x(10/100)
= 1.1x - 1.1x × 0.1
= 1.1x - 0.11x
= 0.99x
As the original value was x and now it is 0.99x, the value has decreased.
Total percent loss = ((x-0.99x)/x)*100
= 0.01*100
= 1%
The total fall in the share is 1 percent. Hope that answer your question
