Can anyone please recommend a good source to learn this concept? I watched the video from EmpowerGMAT on mixture problems and found it very helpful, but it didn't touch on replacement mixture problems. I still can't seem to understand this at all.
Thanks!
In the upper right corner is a search bar.
Enter "is replaced", and you'll get a selection of replacement/mixture problems.
Many mixture problems can be solved easily with an approach called
alligation.
To get a list of problems that I've solved with alligation, enter "alligation" and "gmatguruny" into the search bar.
