Question
Train M, ‘x’ metres long crosses (x – 32) metres
long platform in 20 seconds while train N having the length (x + 32) metres crosses the same platform in 25 seconds. If the speeds of both trains are same then find the value of ‘x’.Solution
Total distance travelled by train M = (2x – 32) m Total distance travelled by train N = (x + 32 + x – 32) = 2x m According to question, => (2x – 32)/20 = 2x/25 => 50x – 800 = 40x => 10x = 800 => x = 80 m
