thumb_How to solve difficult SSC CGL profit loss problems in a few steps 3

Usually profit and loss problems do not come difficult, variations are few and with a bit of grounding on concepts you can solve any of this category of problems easily. That's why this one surprised us. At the first glance there seemed to be too many variables and the problem unsolvable. But when we looked deeper we discovered the clues to elegant solution one by one...

HCF and LCM

thumb_hcf and lcm

Highest Common Factor or HCF is the largest factor that divides two or more numbers under consideration. It is the largest among all the factors common to the set of numbers under consideration. The LCM is the smallest number that is divisible by the set of given numbers. In other words, LCM is the least common multiple of the set of given numbers...

Numbers, Number System and basic arithmetic operations

thumb_Number system

Numbers form the very foundation of Mathematics whereas zero and place value mechanism together make it possible to form any number, however large or small it may be. After formation of numbers, the four basic arithmetic operations addition, subtraction, multiplication and division transform the numbers using again place value system as a base mechanism. On this foundation Mathematics grows further..
