<p>Let the numbers be 2x, 3x and 4x</p>

<p>According to the question sum of their squares is 2349</p>

<p>⇒ 4x<sup>2</sup> + 9x<sup>2</sup> + 16x<sup>2</sup> = 2349</p>

<p>⇒ 29x<sup>2</sup> = 2349</p>

<p>⇒ x<sup>2</sup> = 81</p>

<p>⇒ x = 9</p>

<p>Required average = (2x + 3x)/2 = 5x/2</p>
