Question

The sum of two numbers is $60$. The greater number is three times the smaller number. Find the numbers.

Answer 1

Let $x$ be smaller number and $y$ be larger. Then, according to question
$x+y=60$ ...$\left(i\right)$
$y=3x$ ...$\left(ii\right)$
from $\left(i\right)$ and $\left(ii\right)$
$4x=60$
$\Rightarrow x=15$
$\therefore y=45$
Therefore, the numbers are $15,45$
