Question

1/8th of the passengers of a train were children if there were 40 children travelling on a train on a certain day. how many adults were there in that train that day.

Answer 1

Let the total no.of passengers travelling by the train be x
then x/8 of them are children
given that there were 40 children
⇒ x/8 = 40
⇒ x = 40×8
∴ x = 320
∴ The total no.of passengers = 320
No.of adults = total - no.of children
= 320 - 40
= 280
∴ There were 280 adults in that train.
