Answer 1

If, Sanchit's present age is "y" years, then:

1. What will be her age 9 years from now?

Ans: Just add 9 to Sanchit's present age, i.e. (9+y) years.

2. What was her age 2 years ago?

Ans: Subtract 2 from her present age, i.e., (y-2) years.

3. Her Grandmother is 4 times her age. What is her grandmother’s age?

Ans: Sanchit's present age = y years

Her grandmother's present age is 4 times Sanchit's present age, i.e., 4y years.

4. Sanchit's grandmother is 5 years younger than her grandfather. What is her grandfather’s age?

Ans: Sanchit's grandmother's age = 4y years

Sanchits grandmother is 5 years younger than her grandfather.

Meaning, Sanchit's grandfather is 5 years older than her grandmother.

Sanchit's grandfather's present age is (4y+5) years.
