Description


Description :- a simple graphic based tutorial(series) for understanding and solving "quantitative aptitude"(numerical ability questions) which you can use for various tests(sat, gre, gmat, cat, gate ...etc) or for general understanding.


and "quantitative aptitude by r.s. aggarwal" was the book that's used while making this series. and i highly recommend every one to go through it once, it has got a huge collection of problems with solutions.
