Hi, please help..

At Station A, the ratio of the number of children to the number of adults on a train was 4:5.
At the next station, 12 children alighted and 10 adults boarded the train.
The ratio of the number of children to the number of adults on the train then became 7:10.
How many children were on the train at first?

Thank you.
