The number of entries in a booklet is N. In the first year, this number is increased by x\% and in the next year it is decreased by x\%. What will be the number of entries in the booklet at the end of two years?
- A. Less than N ✓
- B. Equal to N
- C. More than N
- D. It depends on the value of N
Correct Answer: A. Less than N
Explanation
A sequential increase of x\% and decrease of x\% always yields a net decrease of \frac{x^2}{100}\text{\%}. Hence, the final amount is strictly less than the original value N.
