The train crosses two platforms of lengths 1000 m and 600 m in 80 seconds and 60 seconds respectively. What is the length of the train?

720 m 600 m 540 m 400 m

600 m

Let length of train = L meter According to question , \(\frac{1000 + L }{80}\) = \(\frac{600 + L }{60}\) \(\frac{1000 + L }{4}\) = \(\frac{600 + L }{3}\) 2400 + 4L = 3000 + 3L L = 600 m So , Length of train is 600 m
