Correct Answer - Option 3 : 75
Given:
Total people travelling by the train = 1200
Calculation:
A group of 1 captain and 15 soldiers = 16 people
Total number of groups of 16 people = 1200/16 = 75
Now, each group comprises of 1 captain,
So, number of captains in 75 groups = 75
∴ Total number of captions = 75
