level 2 puzzles

Level 2
These are bit difficult ones, u can use ur pen and paper to get with them.
1.

On the board I've written a problem in long division. I've substituted X's for all of the numbers
except the lucky 7's. It's your job to reason out what these numbers were and to write them back into the
expression.


2.

Place two inverted plastic glasses close
enough together so that you can prop a stick match between them about halfway up, as shown. Now, you have to remove one glass and the match will
remain suspended in air. You may not touch the match
with anything other than the second match on the table,
and you must do that prior to removing the glass.



3.
While checking his supplies, Cy Corncrib noticed something interesting about his flour sacks. The sacks were
stacked three to a shelf and numbered one through nine. On shelves one and three, he had a single sack next to a pair of sacks, while the middle shelf held three sacks grouped together. Now, if he multiplied the number on the single sack (7), by the number on the pair next to it (28), he got 196, the number on the middle sacks. However, if he tried multiplying the numbers on the third shelf, (34) and (5), he got 170. Cy then came up with this problem: How do you rearrange the sacks, with as few moves as possible, so that
 hen you multiply each pair by its single neighbor, you will come up with a product equal to the number on the
middle shelf?
