Domanda 16 di 80
A street of houses is numbered starting on one side with 1,2,3,4.... At the far end the numbers continue down the other side in the opposite direction so the largest number is opposite number 1. The houses are of identical widths so each house has another directly opposite it. If number 17 is directly opposite number 56, how many houses are there in the street?
