    Explanation:

    28 years.

    • F + Se = 70...(1)
    • F+ Ys = 64.....(2)
    • Se+Ys = 34....(3)
    • Eq1 - eq2
    • We get
    • Se - Ys = 6......(4)
    • Add eq 3 and eq 4
    • Se-Ys = 6
    • Se+Ys= 34
    • 2Se =40
    • Se =20
    • :. Se-Ys = 6
    • Ys= Se-6 =20-6 = 14
    • F + Se = 70
    • F = 70-20 = 50
    • Avg of F+Ys+Se = (50+14+20)/3
    • =84 /3
    • =28 yrs.
