Question

40% of the passengers from a train got down at station 75% of the remaining got down at station if the remaining 12A taken at the station how many passengers were there in the train

Answer 1

Let the total percentage at starting of the bus=100%

Then 40% got down at station X, So remaining in the bus=60%

Then 75% of the remaining got down at station Y= 60% -75% of 60% 

Remaining passengers= 60%-45%
=15% 

So 15% passengers= 12 passengers

So 100% passengers= 80 passengers.
