Your cousin is 26 yr older than your sister. The product of their ages is 560. How old is your sister?

  • Math -

    sister age = s
    cousin age = c
    c - s = 26
    c s = 560 so c = 560/s

    560/s - s - 26 = 0
    560 - s^2 - 26 s = 0

    s^2 + 26 s - 560 = 0
    solution is a complex number, no real solution is possible.
