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?
Answer & explanation
Correct answer: option 2
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
