Rani will be twice Raja’s age in $3$ years when Raja will be $40$. How many years old is Rani now?

1. $20$
2. $80$
3. $77$
4. $37$

Let’s say the Present age of Rani $= x$ years

The present age of Raja $= y$ years

Rani will be twice Raja’s age in $3$ yeas when Raja will be $40.$ That means AFTER $3$ years,

$x+3 = 2(y+3)$

given$: y+3=40.$

So, $x+3= 80$

$x=77.$
