Also the questions related to the concepts are discussed simultaneously. This is NUMBERS ( PART II ) where half of the concepts of numbers have been covered including HCF, LCM, divisibilty rule, successive division, Chinese remainder theorem and other imprtanat topics. The other half of the concepts are discussed in NUMBERS ( PART I ) which is the previous course.
