hey guys,

i have started this thread in the hope of helping you to develop your strengths and work on your weaknesses and at the same time have fun.....

well with this same motto my college began these spl. classes to improve our aptitude strength leaving aside the fact we were still in our 2nd year.πŸ˜”

but it was not as it was expected.....it was all fun....😁

i decided to share some of those questions we encountered with you in this thread.:smile: :smile: :smile:

hope it helps you...

    is it right?

  • cooltwins

    now to go on to the next set of questions.... πŸ˜›

    4)if x men, working x hours per day, can do x units of work in x days then y men, working y hours per day would be able to complete how many units of work in y days?
    (a) X^2/y^3 (b) x^3/y^2 (c) y^2/x^3 (d) y^3/x^2


    ^- to the power of.

    5)the front wheels of a wagon are 2(pi) feet in circumference and the rear wheels are 3(pi) feet in circumference. When the front wheels have made 10 more revolutions than the rear wheels how many feet has the wagon travelled?
    (a)30(pi) (b)60(pi) (c)90(pi) (d)150(pi)


    (pi)-3.14

    cooltwins5)the front wheels of a wagon are 2(pi) feet in circumference and the rear wheels are 3(pi) feet in circumference. When the front wheels have made 10 more revolutions than the rear wheels how many feet has the wagon travelled?
    (a)30(pi) (b)60(pi) (c)90(pi) (d)150(pi)


    (pi)-3.14

    Let x be the distance moved...
    so the first wheel moves x/2(pi) revolutions.
    2nd one moves x/3(pi) revolutions.

    if the diff. in revolutions is 10
    then 10=x/2(pi)-x/3(pi) =x/6(pi) => x=60(pi).

    so the answer is (b) 60(pi)
    hope it is correctπŸ˜€

    cooltwinsnow to go on to the next set of questions.... πŸ˜›

    4)if x men, working x hours per day, can do x units of work in x days then y men, working y hours per day would be able to complete how many units of work in y days?
    (a) X^2/y^3 (b) x^3/y^2 (c) y^2/x^3 (d) y^3/x^2


    ^- to the power of.

    work done by the x-group =x*x*x-------(1)
    work done by the y-group =y*y*y-------(2)

    (2)/(1)=>
    y^3
    x^3

    but units of work done by x-group is x
    let units of work done by y-group be a
    =>
    y^3=a
    x^3 x

    =>a=y^3 / x^2

    so is the solution
    4)y^3 / x^2

    the distance s=42km.
    the time taken is,t=1hr40min48sec=1.68hr

    speed is v=s/t
