- 1. In a hoel, 60% had vegetarian lunch while 30% had non-vegetaian lunch and 15% had both types of lunch. If 96 people were present, how many did not eat either type of lunch ?
Options- A. 24
- B. 30
- C. 36

Correct Answer: 24
Explanation:
n (A) = (60/100 * 96) = 288/5, n (B) = (30/100 * 96) = 144/5, n (A ? B) = (15/100 * 96) = 72/5.
n(A ? B) = n (A) + n (B) - n (A ? B) = 72.
