What is the time taken by train to go from Station A to Station B?
Statement I: If the train increases its speed by 20%, then it reaches 40 minutes earlier.
Statement II: If the train decreases its speed by 40%, then it reaches 90 minutes late.
From I : distance/ (120s/100) = t – 40 D=(t-40)×6s/5 From II : distance/(60s/100) = t + 90 D=(t+90)×3s/5 both statement given distance are same . (t-40)×6s/5=(t+90)×3s/5 t=170min
