Question
Train M, βxβ metres long crosses (x β 35) metres
long platform in 28 seconds while train N having the length (x + 35) metres crosses the same platform in 32 seconds. If the speeds of both trains are same then find the value of βxβ.Solution
Total distance travelled by train M = (2x β 35) m Total distance travelled by train N = (x + 35 + x β 35) = 2x m According to question, => (2x β 35)/28 = 2x/32 => 64x β 1120 = 56x => 8x = 1120 => x = 140 m
