This is possible because Adam had remarried.

Let us simplify boxes by naming them from 1 to 10.
Now the trick here is to pick different number of balls from different boxes. So to simplify things, we will pick balls corresponding to box number.

Thus, pick 1 ball from Box 1, 2 balls from box 2, 3 balls from box 3 and so on. You will have 55 balls altogether. Now, put them all in the balance.

If all balls were weighing accurate 10 grams, the total weight of the 55 balls would have been 550 grams. But one of the box must have had the defective balls.

Suppose if the defective balls were in box number 2, then the total weight will be 2 grams less than 550. If the defective balls were in box 8, the total weight will be less than 8 grams from 550. In this way, you will be able to identify which box has the defective balls.

It will take him an hour to take all five tablets.

Suppose he takes the first tablet at 9:00 pm. He will take the second tablet at 9:15, the third at 9:30, the fourth at 9:45 and the last at 10:00.

1/2

In the house on the left, there are three possibilities:
Younger Older
Girl Boy
Boy Girl
Boy Boy

We cant have a girl-girl option because it has been mentioned that there is at least one boy in that house. Now all these outcomes are equally likely, and we have two events with girls, the chances of having a girl in the left house is 2/3.

In the house on the right, there are two possibilities because we already know that the older child is a boy:
Younger Older
Girl Boy
Boy Boy
Here the chances are 1/2.

Thus you must choose the house on the left for better chances at winning.

18

Assume that the total number of can before distribution were 3*C

After distribution, each one of them had C cans then.

Each one of them drank four cans and thus (C-4) cans remained.

Now according to the questions we can frame the following equation:

3 * (C-4) = C
(3 * C) – 12 = C
2* C = 12
C = 6

Thus, the total cans before distribution were 3 * C = 3 * 6 = 18.

As you can see in the picture, the strategy used here is to cover the border first and then move to the inner squares.

It was a women world cup. The country had strict rules against female nudity and thus, the players were arrested.

The figures shows how to do it.

Bertie is the mole.  Both Albert and Cedric are telling the truth.  Hence, when Albert said, “Bertie is a mole,” he was telling the truth, and giving you the correct answer.  When Bertie said, “Cedric is a mole,” he was lying, as he himself is a lying mole.  When Cedric responded, “Bertie is lying,” he was telling the truth, and also affirming that Bertie was lying.

In the second case, if there were 2 moles, the identifications would be a direct inverse.  Both Albert and Cedric would be moles, and Bertie would be telling the truth.
