let x,y be the present ages of pushpa and Rita
given,x-y=2
x=y+2----------(1)
two years ago....
pushpa's age will be x-2
by (1) =y+2-2=y
rita's age will be y-2
given pushpa is twice the age of Rita
y=2(y-2)
y=2y-4
y=4----(2)
by substituting (2) in (1)
we get,x=y+2
x=4+2
x=6
therefore present age of pushpa is 6 years
I hope it will help u;)
