If A = {2, 4, 6, 8} and B = {4, 8, 12}, then A ∩ B is:

Out of 60 people, 40 speak Nepali, 30 speak English and 25 speak both. How many speak neither language?
सही उत्तर: घ) 15
Speak at least one = 40 + 30 − 25 = 45, so neither = 60 − 45 = 15. Forgetting to subtract the 25 who speak both would wrongly give more speakers (70) than people (60).

In a class, 30 students like tea, 25 like coffee and 10 like both. Every student likes at least one. How many students are there?
