1 - True. If a number is divisible by 12 it's divisible by 6 and thus by 3

2 - False. A rhombus needn't have square angles

3 - False. the second proposition is unrelated to the first one, and doesn't allow us to deduce that cats have fur.

4 - False - We cannot link the first and second proposition in any way to make the third

The number of bottles in a full box is 12.

<u><em>Explanation</em></u>

Suppose, the number of bottles in a full box is $x$

So, the number of bottles in <u>three</u> full boxes $=3x$

Now, two more boxes are added, both of which have <u>one fewer bottle than the other three</u>. So, the number of bottles in these two boxes $= 2(x-1)$

As there were 9 bottles initially and now there are 67 bottles in the fridge, <em><u>so the equation will be</u></em>....

$9+3x+2(x-1)=67\\ \\ 9+3x+2x-2=67\\ \\ 5x+7=67\\ \\ 5x=67-7\\ \\ 5x=60\\ \\ x=\frac{60}{5}=12$

Thus, the number of bottles in a full box is 12.
