Answer 1

The present age of Kanika is "45 years".

Step-by-step explanation:

Let the present of  Kanika's father = x years and

the present of  Kanika = y years

To, find the present age of Kanika = ?

According to question,

$(x+15)=(y+15)\times 5$

⇒ $x-5y=-60$      ....... (1)

Also,

$(x+15)=(y+15)\times 3$

⇒$x-3y=30$      ....... (2)

Subtracting (1) from (2), we get

$2y=90$

⇒ y = 45 years

Hence, the present age of Kanika is "45 years".
