<h3>What exactly is simplification?</h3>
Simplifying means making something easier to do or comprehend, as well as making something less difficult.
Mashud and Iqbal are security guards at a top-secret federal vault. They each work 8-hour shifts, If Mashud begins his shift at 8 PM,
The time will it be after they each have worked 4 shifts;
8 PM + 8 hour =4 AM
4 AM + 8 hour = 12 PM
12 PM+ 8 hour =8 PM
8 PM + 8 hour = 4 PM
Hence, option E is correct.
They will each have worked four shifts by the time it is 8 PM.
