Solution"YES" if he wants a scotch, "NO" if he prefers something else.
The first says "I dont know" because he wants a scotch, but do not know if everybody wants one.
The second says "I dont know" because he wants a scotch, but do not know if the third logician wants one.(he know 1st one wants one, otherwise, he would reply as no)
The last one knows that both wants a scotch and hence can reply as his own preference.
