  1. Answer:

    present time

    Ankit:pooja=4:3

    Ankit age=4x

    pooja age=3x

    after 12 years

    Ankit :pooja=6:5

    Ankit age=4x+12

    pooja age=3x+12

    4x+12:3x+12=6:5

    x=6

    hence

    Ankit age in present time=4×6=24

    pooja age in present time=3×6=18

    four years ago

    Ankit age=20

    pooja age=14

    hence

    Ankit :pooja=10:7
