Answer 2

Step-by-step explanation:

Let the number is= x

Ratio of three numbers product is 5:2:3 this means 5x×2x×3x=810

After solving we get,

30x³ = 810

x³ =810/30 that is 27

By taking cube root both side we get,

x=3

Means the number is : 3×5, 3×2, 3×3

15,6,9

and the sum of these numbers is : 15+6+9= 30
