Answer»

Let present age of Geeta be x and Kamla be y.

Five years agoGeeta's age = 3 (Kamla's age)

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

x - 5 = 3y - 15

x - 3y = -10 . . . . . (1)

Ten years laterGeeta's age = 2(Kamla's age)

(x + 10) = 2(y + 10)

x + 10 = 2y + 20

x - 2y = 10 . . . . . (2)

(1) - (2) -y = -20

y = 20

Substitute in (1)

x - 3(20) = -10

x - 60 = -10

x = 50

Geeta's age = 50 yearsKamla's age = 20 years
