Finally my turn :-\

Next is: There are 4 men in a boat in the middle of the ocean. They have 5 cigarettes and they each smoke one. How do they light them?

To be honest i dont get it :-\, the answer is weird maybe someone can explain it when its been answered indeedy weedy :-\

 

[Dagless]

With a lighter?

 

[Woodrow]

I don't think this one was posted yet. The answer is apparant if you understand the question.

A man steps out of his house walks 3 miles south, than 3 miles west and then 3 miles north which brings him back to his house. He sees a bear on his front porch.

What color is the Bear?

They throw out one cigarette, which makes the boat lighter.

White (polar bears appear white).

[Woodrow]

White (polar bears appear white).

:wa:

Correct. The only place on earth you could walk 3 miles , South, 3 miles west , 3 miles North and be back at your starting point is the North Pole. Therefore the house was at the North Pole and the only bears found at the North Pole are Polar Bears.

Incorrect

They throw out one cigarette, which makes the boat lighter.

:wa:

Correct, for the answer it says :They throw one out of the boat, and it becomes a "cigarette lighter". , i dont get it :-\

 

[Ğħαrєєвαħ]

Ok next is :

A man works in a fruit and vegetable shop. His shoe size is 8, he is 21 years old, his shirt size is Large and he is 6 feet tall. What does he weigh?

A Q on Logic!

He weighs fruits and veggies.

^lol you are correct

orite ill try make it a lil harder

Next is: A car's odometer shows 72,927 miles, a palindromic number. What are the minimum miles you would need to travel to form another?

Ok this seems perfect, i think :-\

That means there's a cigarette's worth in weight removed. "The boat has become a cigarette lighter" is an ambiguous statement; which could either mean its become a lighter for cigarettes, or its become lighter by the weight of a cigarette.

110 miles.

Jazakallahu Khaayr for the explanation akhee, it was helpful!

Foul, not fair, that is math. Math questions are forbidden.

Palindromic Number



A palindromic number is a number (in some base ) that is the same when written forwards or backwards, i.e., of the form . The first few palindromic numbers are therefore are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, ... (Sloane's A002113). The number of palindromic numbers less than a given number are illustrated in the plot above.

The numbers of palindromic numbers less than 10, , , ... are 9, 18, 108, 198, 1098, 1998, 10998, ... (Sloane's A050250). This sequence is given by the closed-form formula


(1)
Banks et al. (2004) proved that almost all palindromes (in any base) are composite, with the precise statement being


(2)
where is the number of palindromic primes and is the number of palindromic numbers .

The sum of the reciprocals of the palindromic numbers converges to a constant (Sloane's A118031; Rivera), where the value has been computed using all palindromic numbers is 3.370001832....

The first few for which the pronic number is palindromic are 1, 2, 16, 77, 538, 1621, ... (Sloane's A028336), and the first few palindromic numbers which are pronic are 2, 6, 272, 6006, 289982, ... (Sloane's A028337). The first few numbers whose squares are palindromic are 1, 2, 3, 11, 22, 26, ... (Sloane's A002778), and the first few palindromic squares are 1, 4, 9, 121, 484, 676, ... (Sloane's A002779).

There are no palindromic square -digit numbers for , 4, 8, 10, 14, 18, 20, 24, 30, ... (Sloane's A034822).

Numbers that are not the sum of two palindromes (where 0 is itself considered a palindrome) are 21, 32, 43, 54, 65, 76, 87, 98, 201, 1031, ... (Sloane's A035137). Numbers that are not the difference of two palindromes are 1020, 1029, 1031, 1038, 1041, 1047, 1051, 1061, ... (Sloane's A104444).

You figure it out, you gave me a headache,

 

['Abd Al-Maajid]

110 miles.

:wa:

How did you calculate it? Did you use trial and error method or something else?

Anyways, Geek is going to ask another geeky question, M4L?

 

[أحمد]

How did you calculate it?

It was simple. Original number 72927 has five digits, it needs to be increased by keeping it palindromic (horizontal mirror value should be identical to the number). If you increase the units; you can't get a palindrome without increasing the ten-thousands. As the number consists of five digits (an odd number of digits), you can easily start in the middle and work your way outwards. Increasing the 9 in the hundreds place will increment the thousands. This means you have to increment the tens; so the quickest way is to add 1 to the 9 (in hundreds), which makes 73027, and then add 1 to the tens place to make 73937.

Its basic maths; whenever you're working with a palindromic sequence, you always work your way outwards, just as you work right to left in addition and multiplication.

^ I never heard of palindromic number before. Just yesterday I read about it on wikipedia. Anyways thanks.

Next question....?

 

[أحمد]

On the Earth I am dead though I live on the moon. I am in no crater and I'm in every boom. What am I?

It was long time since I solved a math problem, you guys just remembered me the math days :exhausted

here is one easy question :

There are 2 trees in a garden (tree "A" and "B") and on the both trees are some birds.

The birds of tree A say to the birds of tree B that if one of you comes to our tree, then our population will be the double of yours.

Then the birds of tree B tell to the birds of tree A that if one of you comes here, then our population will be equal to that of yours.

Now answer: How many birds in each tree?

Tree A has 5 birds and tree B has 4 birds...:?
