GA young lady being asked her age, answered, eff
add half of the my age as my age the
sum will be one half of my age." How old was she
A:-She was 10 years old. The square root of 16 =
one half of = q IS of Is e. plus s one half of
her age.
Said Robin to Richard eff come
To the age that you are brother mine,
Our ages united would amount o the sum
Of years making ninety nine
Said Richard to Robin "Thats certain, it be fair
For to look toward far,
then shall be double the age that you were
When was the age that you are. &C Il. II.
A:-Let = Richards age and y = Robins age
Then TX plus x SO
and by x) 2y-y
Therefore = As and = Sc Ans.-C. H. H.
Q:-Would you please tell how submarine gets down
under the surface?-L. K
A:-The first essential vessel to enable it to navigate
below the surface of the that be sufficiently

O-Was first landing of allied troops in Greece done
with the permission of the Greek Government
collectively with that of individual in the Greek Cab
net that person acting within his constitutional
right as a Government oficia
A:-As to what happened the following outline from the
'New International Yearbook 1915 Dodd Mead gives
the facts:
''The Greek Government confronted by prob
lem first whether should fulfill her treaty obligations
by aiding Serbia against Bulgaria. second whether Greece
should allow Anglo-French through Greek terri
tory on their way fight with the Sebians On these
points the King and the Premier Venzeos absolutely
disagreed the latter part of September 915 NJ Venizelo
not only Greek mobilization, September 25 but fur
thermore asked France and England if they willing to
send 15O troops support of Serbia The King how
ever refused consider any such proposition Venizeo
municated Kings refusal to the Entente Powers
s'In reply he received a from the French Minister
October O. announcing that the first contingent French
troops had already arrived Saonka and that other French
and English troops would be through Greek territory
aid Serbia foeder ustifying Greek inerven
ton in favor had occurred Bulgaria had
vet attacked Serbia said NJ Venzeos, protested against
landing of the AngoFrench at Saonika because
Greece still neutral could but be gad however, be-
Serbia. On October however, was compelled to resign as
the King disapproved what had DONE (page 293)
Thus will be that in the Greek Government
sanctioned allied landing Saonca although Venizeos
may be said to encouraged it. The Allies knowing that
they sympathy the Premier and that majority
Greeks back of him, simply went ahead
