Question

On Tuesday, the clock reading when Amar entered office in the morning was the same as the clock reading when he left the office in the evening. How many hours did Amar spend in the office?

• A. 12 hours
• B. 24 hours
• C. 10 hours
• D. 6 hours

Answer 1

The correct option is A 12 hours

The same time reading in AM as that of in PM will always have a difference of 12 hours.
Let’s assume that he reaches office at 10 am and leaves at 10 p.m..
$\Rightarrow$10 p.m - 10 a.m = 12 hours.
Therefore, Amar spent 12 hours in the office.
