Answer 1

Answer-

Tyler must be more than 7 years old, so that the ratio of his sister's age to his brother's age is less than 2.

Solution-  

Let's assume that,

Age of Tyler = x years, then

Age of his sister = (x+3) years and Age of his brother = (x-2) years

As given that the ratio of his sister's age to his brother's age must be less than 2, so

$\Rightarrow \dfrac{x+3}{x-2}$

$\Rightarrow x+3$

$\Rightarrow x+3$

$\Rightarrow 3+4$

$\Rightarrow 7$

$\Rightarrow x>7$

Therefore, Tyler's age must be more than 7, in order to satisfy the condition.
