Correct Answer: 72


Solution : The ratio of the two numbers is 3 : 7.
Let the numbers as $3x$ and $7x$ for some number $x$.
Given that the sum of the two numbers is 180, we can write the equation:
$⇒3x + 7x = 180$
$⇒x=18$
The positive difference between the two numbers $=7x - 3x = 4x=4×18=72$
Hence, the correct answer is 72.
