2. What was her age 3 years back?
3. Sarita’s grandfather is 6 times her age. What is the age of her grandfather?
4. Grandmother is 2 years younger than grandfather. What is grandmother’s age?
5. Sarita’s father’s age is 5 years more than 3 times Sarita’s age. What is her father’s age?

Answer 1

1. Sarita’s age after 5 years from now = Sarita’s present age + 5 = y + 5
2. 3 years ago, Sarita’s age = Sarita’s present age − 3 = y − 3
3. Grandfather’s age = 6 × Sarita’s present age = 6y 
4. Grandmother’s age = Grandfather’s present age − 2 = 6y − 2
5. Father’s age = 5 + 3 × Sarita’s present age = 5 + 3y
