Question:
Kamala would like to complete all her home-work before 10:00 p.m. in order to watch an important TV programme. She has 40 minutes assignment in each of her five prepared subjects. What is the latest time at which she can start and still complete her home-work in the time for the programme? 
Options:
A) 6:40 p.m.
B) 6:30 p.m. 
C) 7:10 p.m.
D) 7:20 p.m. 
Solution:
5 x 40 = 200 minutes = 3 hours 20 minutes.

Now 10:00 \(-\) 03 : 20 = 07:20 p.m.
