  8. X can do a work in 20 days. Y can do the half of the work  in 12 days. Z can do 1/3rd of the work  in 5 days.They were assigned to a task.All started together but X leaves the task 2days before completion and Z leaves the work 4 days before completion.Y is the only person to work untill task is finished.What is the total time(approximately) taken to complete the task?

    D. 10days
    E. None of these
    B.
    X one day work-20days
    Y one day work-12×2=24days
    Z one day work-5×3=15days
    Lets the work finished in d Days.So
    (d-2)/20 + d/24 + (d-4)/15 = 1
    =>d=8.6(approx 8.5)

  9. If x and y are integers ,is x+y an odd number?
    i. x≤y ii. 23<x≤25 iii. 24<y≤26
    A. Only i and ii together are sufficient
    B. Any two of three are sufficient
    C. Only i and iii together are sufficient
    D. only ii and iii together are sufficient
    E. All i,ii and iii are together not sufficient-
    E.
    from (ii) x=24,25
    (iii) y=25,26
    Considering all statements
    x=24,25 and y=25
    Still when x=24,x+y=24+25=49(0dd no)
    x=24,x=y=24+24=48(even no)

  10. Find the wrong number according to the series
    198,150,110.72,42,18
    A. 18
