For me, the best hack is having no alarm clock and waking up naturally (ie a the end of sleep cycle). This simple rule changed my life.
Solution:
At first glance this puzzle seems unsolvable. But it has something weird, and this is the fact of “the last digit of the product of their ages” being a clue. How can something so vague be a clue? Unless it’s not that vague. Let’s explore it a little bit.
We make a table with all possible ages for each daughter and calculate the last digit of their product - i.e. (a*b).mod(10)
We can get rid of half the table (since 6x4 = 4x6) and since the problem says they are not twins, we can also get rid of the main diagonal, the one with the square numbers.
Now let's evaluate each digit on the table, and see what we get.
Let’s start with digit 1: it appears once (on 7x3) and the sum of the factors is 10.
Digit 2 on the other hand, appears 6 times (on 2x1, 4x3, 6x2, 7x6, 8x4 and 9x8) and the sum of factors is 3, 7, 8, 13, 12 and 17
Here is the final table
So, in order for the final digit to be a clue, it must tell us something unique. Looking at this table, we realize only 2 digits fulfill this, the digits 1 and 9. So, if the last digit of the product of their ages is 1, that means they are 7 and 3 years old. And if the final digit is 9, that means they are 9 and 1 years old.
Now we have two possible answers, how to proceed? Well, the problem is not to guess their daughters age, but the sum of it. And since in both cases the answer is 10, that’s your answer.
If you wanna know more about Ark, for real, you can start with my (a bit old) ark explainer and keep a look at arkdev's blog
Yes, helm-wallet.com.
It's there, black on white, not trying to fool anyone:
"Helm is a Liquid wallet that uses Boltz submarine swaps to disguise itself as a Lightning wallet that even your grandma can use."
Hi. I have some shell scripts that fetch articles from a RSS feed (from pinboard.in) and post them daily into nostr, see if it helps:
Example note published:
I have one for you:
A friend of mine has 2 daughters (not twins) under 10 years old and wants you to guess the sum of their ages, but the only clue he gives is that the last digit of the product of their ages is the number of their house's door.
Definitely Ark: you can aggregate thousands of transactions into one single onchain transaction while users never loose control of their funds.
Try https://helm-wallet.com/, the Lightning wallet even your grandma can use.
Your grandma doesn't need to manage any liquidity, it just works.
If you have any issue, reply to this post and I will try to help you.
Sort of.
Unlike Muun, it's a PWA (so no app store censorship) that uses Boltz to perform submarine swaps between Lightning and Liquid (for lower fees). You fully own your funds on Liquid and you send and receive Lightning payments via Boltz.
Give it a try, you can use testnet: https://helm-wallet.pages.dev/
Also, https://helm-wallet.com/ the Lightning wallet even your grandma can use.
Well, imho if it doesn't work in Cuba, it's not Bitcoin.
Helm works in Cuba, how about the other options?
Some custodial solutions don't allow accounts from Cuba, and some non custodial solutions are not available on the Cuban app stores.
Yes, I'm the dev.
Yes, it's like AQUA but focused on simplicity, so no altcoins.
Yes, it's a PWA, which means it's immune to app store censorship.
There's no server involved, you can run it on your own computer.
You can use Tor for extra privacy.
The 1000 sats as minimum amount for swap is a constraint from Boltz.
Helm also inherits the 0.01 sats/vbyte the Boltz is trying on Liquid, so Helm have the exact same fees as AQUA.
