Answer: The present age of Hari is 10 years and that of Anushka is 5 years.

Step-by-step explanation: Given that three years ago, Hari was 5 years older than Anushka and he is now twice as old as she is.

We are to find their present ages.

Let x years and y years represents the present ages of Hari and Anushka respectively.

Then, according to the given information, we have

$(x-3)-5=y-3\\\\\Rightarrow x-8=y-3\\\\\Rightarrow x=y+5~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

and

$x=2* y\\\\\Rightarrow y+5=2y\\\\\Rightarrow 2y-y=5\\\\\Rightarrow y=5.$

From equation (i), we get

x=5+5=10.

Thus, the present age of Hari is 10 years and that of Anushka is 5 years.
