  1. LETTER-FIGURE PUZZLE


A correspondent (c. E. B.) sends the following. It is not difficult, if prop-
erlyattacked:
AXB=B, BXC=AC, CXD=BC, DXE=CH, EXF=DK,


F X H = C J, H X J = K J, J X K = E, K X L = L, A X L = L. Every
letter represents a different digit, and, of course, AC, BC, etc., are two-
figure numbers. Can you find the values in figures of all the letters?

his sheep to Ben, then Claude and Adam would together have the same num-
ber as Ben and Dan together. If, then, Adam gave one-third to Ben, and Ben
gave a quarter of what he then held to Claude, who then passed on a fifth of
his holding to Dan, and Ben then divided one-quarter of the number he then
possessed equally amongst Adam, Claude, and Dan, they would all have an
equal number of sheep.
How many sheep did each son possess?



  1. SELLING EGGS


A woman took a certain number of eggs to market and sold some of them.
The next day, through the industry of her hens, the number left over had been
