Answer 1

Geeta's age 3 years back = x-3
Geeta's age after 5 years= x+5
Her dad's age = 3x + 7
Her grandfater's age = 2(3x+7) = 6x + 14
Her grandother's age = 6x + 14 - 5 = 6x + 9.

Answer 2

Let the present age of Geetha be = x
Geetha's age 3yrs back = x-3
Geetha's age after 5yrs = x+5
Geetha's father's age = (3 × x )+7
                                    = 3x+7
Geetha's GrandFather's age = 2×father
                                               = 2(3x+7)
                                               = 6x+14
Geetha's GrandMother's age = grandfather - 5
                                               = (6x+14) - 5
                                               = 6x+14-5
                                               = 6x+9

Hope it helps :)
