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?
सही उत्तर: ग) 45
n(T ∪ C) = n(T) + n(C) − n(T ∩ C) = 30 + 25 − 10 = 45. 55 forgets to subtract the overlap.

12 = 2²×3, 18 = 2×3², 30 = 2×3×5; LCM = 2²×3²×5 = 180. 90 misses one factor of 2.

A train 150 m long crosses a bridge 250 m long in 20 seconds. The speed of the train is:
सही उत्तर: ग) 20 m/s
Distance covered = train + bridge = 400 m, so speed = 400/20 = 20 m/s. 12.5 m/s uses only the bridge length.
