    Answer:The present age of both of them are Christopher = 42 years, and Ishaan = 84 years.

    Step-by-step explanation: Solution:

    Let present age of:

    Christopher =

    x

    yrs

    Ishaan =

    2

    x

    yrs (given that Ishaan is 2 times as old as Christopher)

    35 yrs ago:

    Age of Christopher = (

    x

    - 35) yrs

    Age of Ishaan = (

    2

    x

    - 35) yrs

    According to question, 35 yrs back, Ishaan was 7 times older than Christopher.

    Therefore

    7 X (

    x

    - 35) = (

    2

    x

    - 35)

    7

    x

    - 245 =

    2

    x

    - 35

    7

    x

    -

    2

    x

    = 245 - 35

    5

    x

    = 210

    x

    = 42

    So present age of Christopher =

    x

    = 42 yrs

    &

    Present age of Ishaan =

    2

    x

    = 84 yrs

    Check your solution:

    As 84 is 2 times of 42 so Ishaan is 2 times older than Christopher.

    35 yrs ago, Christopher was (42 - 35) = 7 yrs old and Ishaan was (84 - 35) = 49 yrs old so Ishaan was 7 times older than Christopher then.
