Answer Posted / harry
For the given dimensions of wall i.e. 12*11 , imagine that the pair meet at the point where Bal doubles back.
Then we have
30 + d = 11*(46 - d)/8
d = 14
So Bal walks for 14 metres, doubles back for 15 metres, then turns round and walks another 15 metres, thus returning to where he doubled back. Bal has now walked 44 metres and Pal has walked 32 metres.
In other words, they have collectively walked 76 metres around a perimeter of only 46 metres.
