Please help with this question, m.thanks in advance
Gordon had two crates containing both lemons and pears in each crate.
The ration of the number of lemons to that of pears in Crate A was 7:5.
The ration of the number of lemons to that of pears in Crate B was 3:1.
There was an equal number of fruits in each crate.
Gordon transferred 1/5 of the pears from Crate A to B.
He then threw away 84 lemons from Crate B.
The ration of the number of pears to that of lemons in Crate B then became 5:6.
What was the total number of fruits in both crates at first?
