Logical Reasoning is considered to be one of the most challenging sections for any competitive exam. The trick is to locate the answer within the clues hidden in the problems. The 2nd edition of the revised and updated book “Koncepts of LR - Logical Reasoning for CAT, XAT, IIFT, CMAT, Bank PO and other aptitude tests” is the benchmark in the learning process for Logical Reasoning.
