• A. 4 hours 11 minutes
• B. 4 hours 12 minutes
• C. 4 hours 36 minutes
• D. 4 hours 24 minutes

Answer 1

The correct option is C 4 hours 36 minutes

Original time :- 11:22 A.M.
Present time:-01:34 P.M.in 12-hour format
In 24-hour format it will be 13:34
Hence, the time taken for playing = (13 - 11) hours (34 - 22) minutes = 2 hours 12 minutes
Time taken to sleep = 2 hours
total time taken for playing and sleeping
= 2 hours 12 minutes + 2 hours
= 4 hours 12 minutes
Time at which Alex started studying
= 01:34 + 2 = 03:34
Time taken for studying
= 03:58 - 03:34
= (3 - 3) hours ( 58 - 34) minutes
= 24 minutes
Therefore, total time taken
= 4 hours 12 minutes + 24 minutes
= 4 hours 36 minutes
