Today is my birthday. I am now N years old. You can work out N from the following:
- N is a prime number;
- The last time my age was a prime was six years ago (i.e N-6 is prime and no other numbers between N-6 and N are prime);
- N is not a member of any twin-prime pairing: see the definition of a twin prime if needed;
- You can assume that N is less than 50 😀
There is only one unique solution to the above.
And Happy 40th Birthday to Kylie, too.
37?
PermalinkAren’t you just the same age as me now?
PermalinkUnsolvable! age[davee] is surely defined to be >50? 😛
I think you’re about a year younger than my mum.
Permalink/me boots sward into orbit…
Permalinkmattj: Yep, that’s right 🙂
PermalinkOops, I was out. Make that 11 years younger. 🙂 I had 47, with 41 being the previous prime, which is just not true (43). 🙁
PermalinkI got it right \o/
Permalinkyoung wipper-snapper, happy birthday for yesterday anyways.
