Mixtures and Alligation Concepts for CAT Exam Preparation

May 15th, 2018 by

The questions on Mixtures and Alligations are asked repeatedly in CAT and keeping the past year trends in mind, one or two questions are asked every year. We have seen the concept used in some of the Data Interpretation questions as well, so this cannot be overlooked.  Let us begin with the subject matter on this topic.

Application of LCM (Lowest Common Multiple) in solving CAT Quantitative Aptitude Problems

May 14th, 2018 by

While most students are comfortable with the concept of HCF (Highest Common Factor) and LCM (Lowest Common Multiple), they somehow fail to apply it when required.

This question is a symbol of everything that is wrong with rote learning. HCF and LCM are concepts that students start learning as early as the 5th class in school (may be even earlier in some cases). The problem occurs because a few of them forget how the concepts need to
