Compound Interest Problems


!
This post is a part of the Special Questions Directory focusing on Quant topics traditionally neglected and not covered by conventional sources but still tested on the GMAT. Many of these are above average difficulty questions

Compound interest questions are quite often for the test. Many of them involve quite ugly numbers and tedious math, which should be an indication that they can be solved with a shortcut approach or approximation.
