Question

Alex's elder brother is $y$ years old, and Alex is $5$ years younger than his brother. What is the age of Alex?

• A. $y+5$
• B. $5-y$
• C. $5y$
• D. $y-5$

Answer 1

The correct option is D $y-5$

$\underset{–}{\text{Given:}}$
$\bullet$ Alex's elder brother's age $=y$ years.
$\bullet$ Alex is $5$ years younger than his brother.

Hence, if we subtract $5$ from Alex's elder brother's age, we will get Alex's age.

$\therefore$ Alex's age $=(y-5)$ years

Therefore, option (d) is the correct one.
