Question

Hi will appreciate if I could get help with this question:

There are 640 stamps in 2 envelopes altogether.1/3 of the stamps are transferred from envelope A to envelope B and then 1/3 of the stamps in envelope B are transferred to envelope A. As a result, the number of stamps in envelope B is 1/3 of the number to stamps in envelope A. Find the number of stamps in envelope A at first.

Thanks!

Answer

This is a Before After question. 

 

     A         B         Total      
After 12u    4u    
Before 2   10u 6u    
Before 1 15u 1u 16u  

16u = 640

1u = 40

15u = 15 × 40 = 600
