A field supervisor is reviewing 60 pilgrims, of whom 35 have accommodation confirmation, 42 have transport confirmation and 25 have both. How many have exactly one confirmation?
- 25
- 26
- 27
- None of these
Explanation
Total = 60 pilgrims
Accommodation = 35
Transport = 42
Both = 25
Step 1: Only accommodation
= Accommodation - Both
= 35 - 25 = 10
Step 2: Only transport
= Transport - Both
= 42 - 25 = 17
Step 3: Exactly one confirmation
= Only accommodation + Only transport
= 10 + 17 = 27
