An office opens at 10 AM and closes at 5 PM. The lunch interval is for 30 minutes. The ratio of lunch
interval to the total period of office hours is
-
- 1 : 7
- 1 : 14
- 7 : 1
- 14 : 1
Correct Option: B
Total working hours of office
= From 10 a.m. to 5 p.m.
= 7 hours
Lunch interval = 30 minutes
∴ Required ratio = 30 minutes : 7 hours
= 30 minutes : (7 × 60) minutes
= 1 : 14
