Question

Take Sarita’s present age to be $\mathrm{y}\mathrm{years}$. Sarita’s grandfather is $6$ times her age. Her grandmother is two years younger than her grandfather. What is grandmother’s age?

Answer 1

Given, the present age of Sarita $=\mathrm{y}\mathrm{years}$

According to the question, Sarita’s grandfather is $6$ times Sarita's age.

Sarita's grandfather's age $=6\times \mathrm{y}$

$=6\mathrm{y}\mathrm{years}$

Since Sarita's grandmother is two years younger than her grandfather.

Then Sarita's grandmother's age $=(6\mathrm{y}-2)\mathrm{years}$

Therefore, the age of Sarita's grandmother is $(6\mathrm{y}-2)\mathrm{years}$.
