Out of 480 employees, 10% got a salary increase while 20% got a travel allowance increase. How many employees did not get any increase?
A step-by-step solution is:
336
480 x 10 / 100 = 48 employees got a salary increase.

480 x 20 / 100 = 96 employees got a travel allowance increase.

So a total of 48 + 96 = 144 employees got an increase.

Therefore, 480 - 144 = 336 employees did not get any increase.

The answer: 336
