C Correct answer
Explanation

Let the initial salary be 100. After 40% reduction, it becomes 60. After 50% increase, it becomes 60 * 1.5 = 90. The net loss is 100 - 90 = 10, which is 10%.

AI explanation

Assume the starting salary is 100. A 40 percent reduction lowers it to 60, and a subsequent 50 percent increase raises it by 30 to 90. The final salary is 90, which is a 10 unit drop from the original 100. The overall loss is 10 percent.
