Any idea of the answer? Look, here is another thinking question--
You have 4 identical ice trays which can hold 16 cubes(8X2). You have an old fashioned refrigerator in which you can stack the ice trays only one above another and not one beside another. It takes 5 minutes to freeze one complete ice tray. In what minimum time can you freeze all the water in the ice trays? You cannot fill all of them and stack them one over another at once because the water in the lower tray overflows. If the trays could be kept side by side (though it cannot be), it would take 5 minutes to freez them all.
IF YOU READTHE QUESTION CAREFULLY, YOU ALREADY GOT A HINT OF THE ANSWER.
Abs, you're killing me.
