Official Solution:
In a room of 100 people, 99% are left-handed. How many left-handed people must leave the room to reduce the percentage to 98%?
A. 1
B. 2
C. 49
D. 50
E. 98
There are 99 left-handed people and 1 right-handed person in the room. After some number of left-handed people leave, the right-handed person will still remain and must represent 2% of the remaining people. Since 2% is equivalent to \(\frac{1}{50}\) of the total, the number of remaining people must be 50 (with the 1 right-handed person making up 2% of this new total). This means that 50 left-handed people must leave the room to bring the percentage of left-handed individuals down to 98%.
