Question

Mr Sahoo attended a 1-day workshop from 09:15 a.m. to half five in the evening. The workshop included a $1\frac{1}{4}$ hour lunch break, two 15 minutes tea breaks and 13 activities, each of equal duration. Calculate the duration of each activity.

• A. $30$ minutes
• B. $20$ minutes
• C. $25$ minutes
• D. $40$ minutes

Answer 1

The correct option is A $30$ minutes

Total time of the workshop =$8$ hours and $15$ min

$=8\times 60+15=495$ min

Total time of tea break = $30$ min

lunch break time = $75$ min

hence time available for 13 activities

$=495-75-30$ $=6$ hours and $30$ min

$=390$ min

So, time devoted to each activity $=\frac{390}{13}=30$ min
