The age of ramesh and rahim are in the ratio 5:7. If ramesh was a years oldr and rahim was a years younger,the age of ramesh would have been twice age of rahim.find their age
plz gve me sltn fst

  • Math -

    if ramesh=x, rahim = 7/5 x
    x+1 = 2(7/5 x - 1)
    5x+5 = 14x - 10
    9x = 15
    x=5/3

    so, ramesh is 5/3, rahim is 7/3

    if ramesh were 5/3+1 = 8/3, and rahim were 7/3-1 = 4/3, ramesh would be twices as old as rahim.

    I think a non-fractional age would have been better. Bogus problem.

  • Math -

    ramesh's present age --- 5x
    rahim's present age ----- 7x

    under the "if" situation:

    5x+1 = 2(7x-1)
    5x+1 = 14x - 2
    x = 1/3
