Question

In this picture you can see 6 coins in the shape of a cross. Moving just ONE coin, can you form 2 lines, each with 4 coins?

Answer 1

Yep, we can. You just need to take out that bottom-most coin and place it on the central coin (here, I mean the centre of the cross). Now, you see that it is in the shape of ' + '.

And there are four coins in each line (one horizontal and one vertical).

Answer 2

Yes, we must keep the bottom most coin over the centre of the cross. The both the lines will have 4 coins each.
