Answer 2

The answer is 68.

Step-by-step explanation:

Let one of the numbers be 'u'.

Then, the other number is three times 'u', i.e. 3u.

So, according to the question, 'u' multiplied by '3u' gives 867.

or, we can write

$u\times 3u = 867$

$3u^2 =867$

$u^2 = \frac{867}{3}$

$u^2 = 289$

So, u = 17.

So, the first number is 17 and the other is 51 (3x17).

Finding the sum of the two numbers: 17 + 51 = 68.
