Present age of:

Christopher = 42 yrs

Ishaan = 84 yrs

#### 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
