FAMILY FUN

To Tell a Person's Age. — If you wish to tell the number that some one may think of when requested to do so, follow this method : Tell him to think of any number, as 23 ; multiply it by 2 (46) ; add' I (47) ; multiply by 5 (235) ; add 5 (240); multiply by 10 (2400) subtract 100 (2300 ; ask for the result ; strike off the two last figures ; and obtain 23. A variation of this is seen in the following method of telling when a person's birthday comes. Tell him first - to write down the day of the month in which lie was born, say January(l); multiply it by 2 (2); add 5 (7); multiply by 50 (350) ; add the day of birth* say 1 (351) ; subtract 250 (101). The last two figures will give the day. of the month on which the person was born; the other figure or figures will give the number of the month. The person giving these results was born on January 1. The age of a person in years may be found by the preceding method; if instead of adding the day of the '•birth the age in years is- added. By a combination of. both methods the age and the exact date of birth may be learned.
