## Try with Hints

Let us take the numbers be $x_i , x_j , x_k ,x_l , x_m$

Now $x_i + x_j + x_k + x_l + x_m = 20$ and again $x_i + x_j + x_k + x_l + x_n = 20$

Can you now finish the problem ..........

From the above relation there are three case arise that....

1)$x_m = x_n$

2)All the integers are equal.

3)$x_{17} =x_{83}$

So the correct answer is $x_{17} =x_{83}$
