Let present age of Preeti be x years.

and Present age of kanika be y years.

According to question ,

x = 5/2 y -----------------------ist

Five Years ago ,

Preeti's age = x -5

Kanika's age = y-5

According to Condition ,

x-5 = 3 (y-5) ------- 2nd

substitute ist in 2nd we get

5/2y - 5 = 3(y -5)

5/2y -5 = 3y - 15

5/2y - 5 +15 = 3y

or 10 = 3y - 5/2y

or 10 = (6 -5)/2y

or 10 = 1/2y

or

Hence Present age of Kanika = 20 years

or x =50

Therefore Present age of Preeti is 50 Years.

Hope this helps you.

Thank You ^_^
