What is the percentage change in the result when we add 50 to a certain number x, instead of subtracting 50 from the same number x?
A. 50%
B. 75%
C. 100%
D. 300%
E. Can't be determined
Answer: Option E
Solution(By Examveda Team)
If we take different values of x then,Let x = 150, then error%
$$\eqalign{ & = \frac{{ {\frac{{ {200 - 100} }}{{100}}} }}{{100}} \cr & = 100\% \cr} $$
Again if x = 100, then error%
$$\eqalign{ & = \frac{{ {\left( {150 - 50} \right) \times 100} }}{{100}} \cr & = 200\% \cr} $$
If we take different value of x,
we get different answer so we can't determine it.
