How would I do this? A sum of money is divided among three persons, X,Y,Z, kn the ratio 10:7:5. If Y gets $14 more than Z, how much will X get and what is the total sum of money? There is no total sum so how do I find it?

  • math -

    Y = Z + 14 and
    7Y = 5Z

    Substitute Z + 14 for Y in the second equation and solve for Z. Go to the first equation to get Y. After that, it should be no problem to find X.

    I hope this helps. Thanks for asking.

  • math -

    Y=Z+14------(i)

    X Y Z
    10 7 5

    FRPM LAST TWO RATIOS:
    5Y=7Z
    FROM EQUATION (i)

    5(Z+14)=7Z
    Z=$35

    NOW PUTTING Z=35 IN (i)

    Y=35+14
    Y=$49

    NOW FROM FIRST TWO RATIOS

    7A=10B
    7A=10*49
    A=$70

    TOTAL MONEY= $70+$49+$35=$154
