Answer 2

Hii friend

The ratio of the numbers are 2:3:4

Let X be multiple to these numbers Then the numbers become 2X , 3X and 4X.

According to question,

(2X)²+(3X)²+(4X)² = 725

4X²+9X²+16X² = 725

29X² = 725

X²= 725/29

X² = 25

X = ✓25 = 5

Therefore,

first number = 2X = 2 × 5 = 10

Second number = 3X = 3 × 5 = 15

And,

Third number = 4X = 4 × 5 = 20.

Hence,

The option (C) 10,15,20 is the right answer.
