The discussion revolves around a problem involving the speed of a train as it passes a pole and a platform, with the goal of determining the length of the train based on the time taken to pass these objects.
Multiple participants express that they arrive at a length of 150 m, indicating a lack of consensus on the correct answer. Some suggest that the source of the alternative answer may not be reliable, while others are seeking clarification on the discrepancy.
Participants are working under the constraints of a homework problem, and there is an indication of confusion regarding the expected answer versus their calculations.

Homework Equations
The Attempt at a Solution
x/15 = (x+100)/25
after solving this equation
x= 150.
but the ans is 180 m ? what should be the correct ans.
A playstore app gives that answer,,, must not be a good appPeroK said:##150m## looks correct to me.
