Question

Vijay is thrice as old as his sister Reena. If the difference of their age is 12 years, find their present ages​

Answer 1

$\mathscr{\red{SOLUTION:-}}$

Let the age of Renna's be = x

Then, Vijays age =3x

Then,

3x - x = 12

2x = 12

x = 6

Hence,

$\boxed{Reena's\:age=6}$

$\boxed{Vijay's\:age=3x=3*6=18}$
