Yep must be 42. I'd need 7 1/2 million years to figure that one myself too!

Is that a serious question? You have three simultaneous equations and six unknown variables, so it's not solvable as written. Needs more information than has been put down there. If you turn round now and tell me there is a solution, it will use more information than was provided.

9L=45W

9(W+L)= G+ (J/L)

Well, lets see.

9W is the call sign for Jet Airways. Jet also operates a low-cost airline called Jet Lite (J/L). G obviously stands for "Goyal", the owner, who first-hand (F/H) likes (L) five weeks (5W) of paid leave (since 9L = 45W, L = 5W).

Hence I believe the answer is 17, 20, 55, 12, 10 which is the number of different aircraft they have on their fleet.

For goodness sake BNT it was obviously a joke. A five year old could see that it couldn't be resolved. He does say:

Well, I'm trying to figure out what the point was. The "72" thing didn't come from the OP, it appears to be a totally unrelated non-sequitur.

If this makes me sound humour-impaired, remember that people do post threads here when they're genuinely in need of help with maths. Maths is not inherently funny, so what is it about those particular equations that I'm supposed to recognise as a joke?

Got the Fibonacci series early on, but was buggered after that. Yup I googooed thereafter. Saw many relationships, just couldn't wrap it up. Came close, though.

Nice one.

Whirls, the answer is correct. The next number in the series is 13112221 if I'm not mistaken :)

Traditionally, binary is 0 AND/OR 1 (I understand your point), but no base was stated or implied.

The sequence, cannot rise above 3. Check it out.

Best. :)

Appreciate the humour much.

Base 2 (ie binary) has only 1s and 0s. Base 3 has 2s, 1s and 0s. Base 4 has 3s, 2s, 1s and 0s etc.

Therefore, a number 13112221 can be in any base above 4. If it's base 4, then, in base 10, it's 30,121.

312211 is 3,492 in Base 4.

Whereas the Fibonacci sequence is

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811, 514229, 832040, 1346269, 2178309, 3524578, 5702887, 9227465, 14930352, 24157817, 39088169.

Therefore, before anyone can say what is the right or wrong answer, we need to know in which base we are counting.

You're reading it wrong, m'lady: It's not a Maths puzzle, it's a word puzzle.

1: One

11 : The above number has one one

21 : The above number has two ones

1211 : The above number has one two (and) one one

111221 : The above number has one one, one two (and) two ones

312211 : Three ones, two twos, one one...

Yep, it's in base 10 Whirls, Bombay Duck and Mike X got it right.

The first row - 1 - contains one 1 -> 11

11 contains two 1's -> 21

21 contains one 2, one 1 ->1211

1211 contains one 1, one 2, two 1's ->111221

so, the next sequence is 312211, and so on....
