In a room of 36 people. 20 players play chase while 28 players play poker. How many players play both?
- A. 45
- B. 45
- C. 45
- D. 45
Answer: Option C
Explanation:
আমরা জানি,
Total = n(A) + n(B) - both + none
⇒ 36 = 20 + 28 - both + 0
⇒ 36 = 48 - both
⇒ both = 48 - 36
⇒ both = 12
Total = n(A) + n(B) - both + none
⇒ 36 = 20 + 28 - both + 0
⇒ 36 = 48 - both
⇒ both = 48 - 36
⇒ both = 12
