Let current age of Geeta be x years

By given current age of Sunita = x

(i) after 4 years?

Age after 4 years = current age + 4

Therefore, Geeta’s age after 4 years = x + 4 years

Therefore, Sunita’s age after 4 years = x + 4 years

(ii) before 3 years?

Age before 3 years = current age – 3

Therefore, Geeta’s age before 3 years = x – 3 years

Therefore, Sunita’s age before 3 years = x – 3 years
