alleryಒಂದು ಕೆಫೆಗೆ 150 ಜನರು ಭೇಟಿ ನೀಡಿದರು. 25 ಜನರು ಚಹಾ ಮತ್ತು ಕಾಫಿ ಎರಡನ್ನೂ, 40 ಜನರು ಚಹಾವನ್ನು ಮಾತ್ರ ಮತ್ತು 60 ಜನರು ಕಾಫಿಯನ್ನು ಮಾತ್ರ ತೆಗೆದುಕೊಂಡರು. ಇವುಗಳಲ್ಲಿ ಯಾವುದನ್ನೂ ತೆಗೆದುಕೊಳ್ಳದವರು ಎಷ್ಟು?
A15
B20
C35
D25
Answer & Solution
Correct answer: D. 25
ಬಳಸಿದ ಮೂರು ಪ್ರದೇಶಗಳು ಒಟ್ಟು 60 + 25 + 40 = 125, ಎರಡೂ ವಲಯಗಳ ಹೊರಗೆ 150 - 125 = 25 ಅನ್ನು ಬಿಡುತ್ತವೆ.
