Dishonest Dealers and faulty weights is an important topic in profit and loss generally asked in all competitive exams. In this topic, we come across such type of problems in which shopkeeper sells the items at cost price but still, he makes a profit on those items. This can be only possible if he gives less quantity to the customer then the indicated on the product.

In the Understanding Confusing Words – Part 1, we discussed confusing words. As discussed Learning New Words – Why, How and Strategies, these words are not directly related to CAT prep for the vocab section or for any MBA exam (so don't expect direct questions based on these words) but knowing the right words and the correct usage will make your job much easier while attempting questions. Let us extend the list with a few more words. Prescribe vs. Proscribe - These similar sounding words have very different meanings. Prescribe is the more common word, and it's often used at the docto

In the last post we looked at some ways to learn new words - reading with context, flashcards, word group lists and studying by comparing words. We had discussed about identifying words that are confused easily. In this post we will look at some examples involving these confusing words. Now, will a misunderstanding cost you marks in the exam? Not necessarily so, because like we discussed last time, no questions simply ask for meanings of words. However, when you’re reading a block of text and reach this word where you are not quite sure of the meaning, that is enough to cause a problem.

Highest Common Factor (HCF) is the largest factor of two or more numbers. The same can be defined algebraically as “ HCF of two or more algebraical expressions is the expression of highest dimension which divides each of them without remainder. HCF is also called GCD (Greatest Common Divisor). HCF can be found either by Factorization method or Long Division Method. However, these two methods are not feasible when we have to find HCF of more than 3 numbers and the numbers are also large. In that case, we can find the differences between the numbers and they can find the HCF of differe

Number of ways of writing a number as a product of two co-primes If N=ap .bq .cr …….., then, the number of ways of writing N as a product of 2 co-primes is 2n-1, where ‘n’ is the number of distinct prime factors of the given number N. Let’s understood
