Question
In how much time will a train running at a speed of 48
km/hr cross the other train running in opposite direction? I. The length of the two trains is 90 metres and 120 metres respectively. II. The speed of the second train is 60 km/hr. Direction (Q.116-120): each of the questions given below has one question and two statements marked I and II. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer:Solution
From I, Distance = 120 + 90 = 210 m. From II, and the question, Relative speed = 48 + 60 = 108 km/hr. ∴ Time = (210 ×18)/(108 × 5) = 7 sec. Therefore, both the statement I and II together are required to answer the question.
