Let's say that the lowest-paid employee at Company X made $20,000 last year, and the highest-paid made $50,000 last year; that fulfills the range of $30,000. If every employee makes 10% more this year, the lowest-paid will make $22,000, and the highest-paid will make $55,000. $55,000 - $22,000 = $33,000, giving us a range of $33,000. This works with any set of numbers; you can do the same thing if the lowest-paid made $50,000 and the highest-paid made $80,000: $88,000 - $55,000 = $33,000. C is the correct answer.

H-L=30,000

10% increase means 1.1x

1.1H-1.1L=33,000

30,000 was range last year
no of emplyee remain same so 10 % increase will add 10 5 to the old salary=30000+10 % of 30000=33000

We can let the lowest salary from last year = 10,000 and the highest = 40,000.

Thus, the new low is 1.1 x 10,000 = 11,000 and the new high is 40,000 x 1.1 = 44,000.

So the new range is 44,000 - 11,000 = 33,000.
