alleryਕੈਫੇ ਵਿੱਚ 150 ਲੋਕ ਆਏ। 25 ਨੇ ਚਾਹ ਅਤੇ ਕੌਫੀ ਦੋਵੇਂ ਲਈਆਂ, 40 ਨੇ ਸਿਰਫ਼ ਚਾਹ ਅਤੇ 60 ਨੇ ਸਿਰਫ਼ ਕੌਫੀ ਲਈ। ਚਾਹ ਜਾਂ ਕੌਫੀ ਵਿੱਚੋਂ ਕੁਝ ਵੀ ਨਾ ਲੈਣ ਵਾਲੇ ਕਿੰਨੇ ਹਨ?
A15
B20
C35
D25
Answer & Solution
Correct answer: D. 25
ਤਿੰਨ ਵਰਤੇ ਗਏ ਖੇਤਰਾਂ ਦਾ ਕੁੱਲ ਜੋੜ 60 + 25 + 40 = 125 ਹੈ, ਜਿਸ ਨਾਲ 150 - 125 = 25 ਦੋਵਾਂ ਚੱਕਰਾਂ ਤੋਂ ਬਾਹਰ ਹੈ।
