Question
Train M, βxβ metres long crosses (x β 25) metres
long platform in 15 seconds while train N having the length (x + 25) metres crosses the same platform in 20 seconds. If the speeds of both trains are same then find the value of βxβ.Solution
Total distance travelled by train M = (2x β 25) m Total distance travelled by train N = (x + 25 + x β 25) = 2x m According to question, => (2x β 25)/15 = 2x/20 => 40x β 500 = 30x => 10x = 500 => x = 50 m
