6. PUZZLE 3:
• If you add the age of a man to the age of his
wife, the result is 91. He is now twice as old
as she was when he was as old as she is now.

7. • Solution : The man is 52 and his wife is 39.
The puzzle refers to the man as once being as old as the wife is
"now." This gives you the first important piece of information; the
man is older than the wife. Second, you know that the two ages
will add up to 91. Third, you know that their difference in age is a
constant variable. You can't, however, assume that they are close in
age, but they must both be middle aged, otherwise it would be
difficult to generate a number as high as 91 under the parameters
of the problem.
So, after gathering this information, and some guess and check
work, you'd find that the man is now twice the age (52) of her age
(26) when he was the age she is now (39).

8. • PUZZLE 4 :

24. A snail is at the bottom of a 20 meters deep pit. Every day the snail climbs 5 meters
upwards, but at night, it slides 4 meters back downwards.
• The Question: How many days does it take
before the snail reaches the top of the pit?

25. • Solution to: Climbing Snail
• On the first day, the snail reaches a height of 5 meters and slides
down 4 meters at night, and thus ends at a height of 1 meter.
On the second day, he reaches 6 meters, but slides back to 2
meters.
On the third day, he reaches 7 meters, but slides back to 3 meters.
...
On the fifteenth day, he reaches 19 meters, but slides back to 15
meters.
On the sixteenth day, he reaches 20 meters, so now he is at the top
of the pit!
• Conclusion: The snail reaches the top of the pit on the 16th day!
