The solution of the question in which the ratio of speeds of trains is calculated by allegation method is wrong. As the ratio of speeds will be directly reciprocal of the time to cross the child. So please elaborate where the allegation method will be used.

here 24 and 15 are time and alligated by mean time that is 15. and since it is reciprocal, it yields ratio of speed. if speed is alligated then it will give ratio of time.

As the times are 24 and 15 so their speeds ratio should be their reciprocal i.e. 15:24 or 5:8. But in slide it has come to be 2:1
