Given
An office opens at 10 a.m. and closes at
5 p.m. with a lunch break of 45 minutes.
Solution
Total timing of office is
= (12 - 10) + 5 hours
= 2 + 5 hours
= 7 hours
= 7 × 60 min [1 hour = 60 min]
= 420 min
Working hours
= 420 - 45 min
= 375 min
(i) lunch break to the total time
= 45 min : 420 min
= 9 : 28
(ii) lunch break to the working hours
= 45 min : 375 min
= 9 : 25
