  1. I. General Aptitude (round 1)
    These are the some qts which I remembered.

    1. Sudoku. you need to fill-up the table using the hint(addition of row, column, diagonal =15) and available cell values. its easy. if you figure it out, you can answer(very easy)
    five questions correctly.

    2.If y=MAX((3x+y),(11x-y)) then what's the value of y?

    3.1 Que. on book arrangement. if u find out the series you can ans five ques. correctly.

    4.2 Ques. on Probability, ages

    5. Ages

    6. Venn diagram --> Out of 100 students, 45 do not know typing, 60 know shorthand. 25 know both 6 do not know anything then find out haw many know both?

    7. if f(y,0)=y+1, f(o,x)=x; f(y,x)=f(f(y,0),f(2*y-1)) then find f(1,1),f(2,3),f(3,0); 3 question based on this. Its very very simple...
