PUZZLE IN REVERSALS.
(
Money Puzzles)
Most people know that if you take any sum of money in pounds, shillings,
and pence, in which the number of pounds (less than L12) exceeds that of
the pence, reverse it (calling the pounds pence and the pence pounds),
find the difference, then reverse and add this difference, the result is
always L12, 18s. 11d. But if we omit the condition, "less than L12," and
allow nought to represent shillings or pence--(1) What is the lowest
amount to which the rule will not apply? (2) What is the highest amount
to which it will apply? Of course, when reversing such a sum as L14,
15s. 3d. it may be written L3, 16s. 2d., which is the same as L3, 15s.
14d.
