Pope has told us that all chance is but "direction
which thou
canst not
see," and certainly we all occasionally come across remarkable
coincidences—little things against the probability of the
occurrence of
which the odds are immense—that fill us with
bewilderment.
One of the
three motor men in the illustration has just happened on one of these
queer coincidences.
He is pointing out to his two friends that the
three
numbers on their cars contain all the figures 1 to 9 and 0, and, what
is
more remarkable, that if the numbers on the first and second cars are
multiplied together they will make the number on the third
car.
That
is,
78, 345, and 26,910 contain all the ten figures, and 78 multiplied by
345
makes 26,910.
Now, the reader will be able to find many similar
sets of
numbers of two, three, and five figures respectively that have the same
peculiarity.
But there is one set, and one only, in which the numbers
have this additional peculiarity—that the second number is a
multiple of
the first.
In other words, if 345 could be divided by 78 without a
remainder, the numbers on the cars
would themselves fulfil this extra
condition.
What are the three numbers that we want?
Remember that they
must have two, three, and five figures respectively.
