Answer 1

hari was 7 then which would mean that Anushka was 2. now he is ten and she is five

because you add three more years to each to get present ages

Answer 2

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

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

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.
