Answer:
15 min
Step-by-step explanation:
Time taken in writing 10 pages is 3.25 hours = 13/4 hours = 13/4 * 60 mins
= 195 min
= 3 hours and 15 mins
Time taken in photocopy 25 copies is 1.5 hours = 3/2 hours = 3/2 * 60 mins
= 90 min
= 1 hour and 30 mins
Total time = 3 hours 15 mins + 1 hour 30 min
= 4 hours 45 mins
Time left = 5 hours - 4 hours 45 min
= 15 min
