We have to add train length because train has to travel the whole length of platform and it has to cover it's own length.

Good explanation. Your right. Question asked is time required to pass the platform and not to come in platform.

How can u know that the pole is on the platform.
if the pole is not on the platform,the ans is 65
240/24=650/t2
t2=65
if the pole is not on the platform,the ans is 65
240/24=650/t2
t2=65

In order to determine the speed the distance of the train can we ignore the distance between the train and the pole.

Why did we add 240 to 650?
Since we only want to find the time taken to cover 650m.
Anyone, please explain me.

As the train has to pass the platform its length need to be considered so they added 240 to the platform length.

I can't understand why we want to calculate both the length of train & length of platform.
Please explain.

Can you tell me, why did we get 240 two times?
(Firstly 240/24, then after 240+650/10) So please explain me.

Its not mentioned in ques that train passes pole and platform both. There is no need to add 240 with 650.

The Answer is 65s, because the question in not mention both pole and platform then why we calculate both?
