Hello Puys and Pirls,

My query is regarding preparing Number systems unit.

Currently I'm Solving CL material for Number Systems. Is that enough or should I move on to Sarvesh Verma(Which I have)? I have gone through TotalGadha's Number Material, however I haven't solved the questions from it.

Please Suggest.

In a football team having 'n' teams each, all the teams play each other twice and get 3 points for a win and 2 points each for a draw. If the total number of points earned by the teams is 217, how many games were drawn?

How to approach these type of problems ? I mean by taking assumption of say 300 pages and then working out or how ?

A little silly question, on which page/chapter I can find Modulus/Inequalities questions in Quantum CAT by Sarvesh K Verma ?

OA : 63,

how do you go about solving these questions ? I mean i understood that the series consists of squares-1 other than 1 and multiples of 3. But unable to figure out the generalization of 1994th term 😞

f(x)= -1^x  where x belongs to[-20.20] and x can take all real values upto 2 decimals

find the probability for the function to be even for a given x?
