Correct Answer: 5 : 61 : 213 : 997


Solution : Let the numbers be $x$, $2x$, $3x$ and $5x$ respectively. According to the question,
$⇒ 2(x + 2x + 3x + 5x) = 44$
$⇒ 11x = \frac{44}{2}$
$⇒ x = \frac{22}{11} = 2$
So, the numbers are 2, 4, 6 and 10 respectively.
Cube of the numbers are 8, 64, 216, and 1000
Subtracting 3 from each term to get the required ratio$= 5 : 61 : 213 : 997$
Hence, the correct answer is 5 : 61 : 213 : 997.
