DAY 465

MATH MAGIC

Add the year of your birth + the year of birth of your child (or any younger relative). Now add to this your age (the age you will be in the current year - even if you have not reached your birthday yet). Next add the age of your child or other relative - also the age he/she will be by Dec. 31 of the current year. What do you get?

Answer:

A number exactly double the current year.

For example:
Today is Sept. 26, 2019.
I was born in 1945.
My daughter was born in 1976.
I will be 74 this year (in Oct.)
My daughter is 43 (already had her birthday).

1945 + 1976 = 3921
74 + 43 = 117
3921 + 117 = 4038  (2x2019)

DAY 464
From Reader's Digest

An old man decided that it was time to divide his herd of 18 camels among his three sons. He kept the camel he loved best for himself and had 17 left. As was the custom, he gave one half the herd to his eldest son, one third to the second, and one ninth to the youngest. How did he do it?

He added his own camel to the 17, making 18 again. 9 camels went to the eldest son, 6 to the second, and 2 to the third. 9 + 6 + 2 =17, so 1 camel was left - the one the old man loved best - and he took it back for himself.

This story illustrates an old Arabian saying: "If you give away that which you love, it will be returned to you."
***********************************************

The saying may be true, but the math isn't. What's wrong?

Answer:

1/2 + 1/3 + 1/9 = 
9/18 + 6/18 + 2/18 = 17/18 - He's one camel short.
