Number of passengers in train A = 700

? Train B has 30% more passengers than train A,

Number of passenger in train B = 700 + (30% of 700) = 910

?30% of the number of passengers of train B is in sleeper class coaches,

Number of passengers in sleeper class coaches of train B = 30% of 910 = 273

According to the information given in the question, in train A, 20% of the passengers are in general conches, one-fourth (i.e. 25%) of the total number of passengers are in AC coaches and 23% of the passengers of train A are in sleeper class coaches

∴ Number of passengers in first class coaches of train A = [100 – (20 + 25 + 23)]% of 700 = 32% 0f 700 = 224

∴ required ratio = 273:224 = 39:32
