    Answer:

    • Sunitha: 35
    • Raseeda: 40

    Step-by-step explanation:

    Both numbers of the ratio units used to express the ratio in ten years are 2 higher than at present. Thus, each ratio unit must stand for 5 years. That would make their current ages …

      Sunitha: 7·5 = 35

      Raseeda: 8·5 = 40

    _____

    If you can’t figure the answer right away from the change in ratio units, then you may need to write a couple of equations:

    • s/r = 7/8
    • (s+10)/(r+10) = 9/10

    These can be translated to standard form, which may make some methods of solution easier:

    • 7r -8s = 0
    • 9r -10s = 10

    These have solution (r, s) = (40, 35).
