    2. Topics to be concentrated in R.S Aggarwal uncle's book
    a) Pipes and cisterns (Only concentrate on methods like simulaneus filling taps and sequentital filling time taken and size of tub )2 problems
    b) Time and Distance (Average distance problems formula-2xy/(x+y) x-first speed y-second speed -1 prob and d=s*t simple problem only 1 so total 2 problems
    c)Numerical calculations simple problem based on (A+B)^2=A^2+B^2+2AB AND (A+B)^3


    But not directly he will ask it using lilavathi story telling the concept at last saying that product of two numbers is something and sum of two numbers is something find sum of squres of that number A+B is given AB is given solve it using A+B whole square formal and get sum of squares 2 problems

    d) A question on hand shake which is from shakus puzzle buk formula is 2^n=n(n-1)/2 number of hand shakes problem 8 people attending party number of hanshakes with cycle means 8*7/2=28 or if u find the word no cycle than answer is 7 one less
