30% passenger from train got down at station A, 70% of the remaining got down at station B, If there are still 1050 passenger in the train, how many passenger were there before station A, provided no one boarded the train at station A and B?
Let us assume that no one boarded the train at station at A and B.
Let,
total passenger before station A = x
30% passengers from train got down at station A.
Therefore total number pf passengers got down at station A = 30% of x = 70% passengers from train got down at station B.
Therefore total number pf passengers got down at station B = Given that there are still 1050 passengers in the train.
Therefore the total number of passengers before station A are 5000.
