Avals:

1. An integer is between 2 and 4. As the minimum number 123456*5=617280 does not fit, and the next minimum 132456*5=662280 is already greater than the maximum possible (654321)

2.3.4 aha.

1 m.b. another 123546 123564 123645 123654 ...

I wrote there at the top --- 12**** x 5 = 6****5

Still at the end there can only be 3 or 5. And the maximum number is 643215.

12 choices:

****:

3465
3645
4365
4563
4635
4653
5463
5643
6345
6435
6453

6543

Avals:

Because:

1. An integer is between 2 and 4. Since the minimum number 123456*5=617280 - does not fit, and the next minimum 132456*5=662280 is already more than the maximum possible (654321)

Well, it seems the next minimum = 123465.

No?

 
MetaDriver:

I thought the next minimum was 123465.

Isn't it?


yes, that's right. Five requires in-depth study :)
 

TheXpert:

There can also only be 3 or 5 at the end. And the maximum number is 643215.

Uh-huh, OK.
 
sergeev:

not fill from scratch, but from 9

Is there a way to do it in 3 pouring from 0 ?
 
Man, I hoped to the last minute that the hockey players weren't building for nothing... Wrong goal.

Then it doesn't work. There is no solution among those twelve.

123465*5= 617325
123645*5= 618225
124365*5= 621825
124563*5= 622815
124635*5= 623175
124653*5= 623265
125463*5= 627315
125643*5= 628215
126345*5= 631725
126435*5= 632175
126453*5= 632265
126543*5= 632715

Leha's a bully. He's mocking.

I got cheated on the ECHO. Phone in hand, a quiz on the echo. By chance the answer pops into my head. Right away I send it back and .... Dick. Not in the first 11 people. This is a speed-texting race and not a bloody quiz. I had a bad day this morning.

And the buckwheat with the...

 
Mischek:

Is there a way to make it in three pours from 0 ?

By the way. The 50g weights have been lost. There's only 200g left.

There is a three-way solution anyway.

 
MetaDriver:

By the way. The 50g weights have been lost. Only 200g is left.

The three-way solution still exists.


You know what, Vova. Don't spoil my mood completely. If it's a joke or a mistake and I waste my time, I'll give you that 200g weight...
