Answers 233- ROBINSON'S AGE
Robinson's age must have been 32, his brother's 34, his sister's 38, and his
mother's 52.- A DREAMLAND CLOCK
The hour indicated would be exactly 23%3 minutes after four oclock. But

from 60 to get the real time.
47. WHAT IS THE TIME?
The time is 63,.~ minutes past IX, when the hour hand is 450/16 (the square

The first time would be 55 ;'43 minutes past twelve, which might also (the
hands being similar) indicate 6o/i43 minutes past one oclock.- THE BROKEN CLOCK FACE

the four parts will sum to 20. The

for trial.
