Solution:

Let us assume that there are m male citizens
Then, the number of females will be (3553 – m)
According to question,
m/9 people received $45
And (3553-m)/12 received $60

Thus, total money spent by the wealthy man = (45 * (m / 9)) + (60 * (3552 - m) / 12)
= 5 * 3552
= $17,760

A Question

Solution:

If you are thinking to hold one chocolate from each box in hand and then balancing weight in bare hands, you are thinking all wrong.

Let us begin by labelling boxes as 1, 2, 3 and so on till 10.

Now pick one chocolate from box 1, two chocolates from box 2, three from box 3 and so on. In total, you will have 55 chocolates now. (1 + 2 + 3 + ..... + 10)

The ideal weight of the chocolates should be 55 * 20 = 1100. However, somewhere in there are the defected chocolate/s.

You can judge that clearly by noting down the result of 1100 - total weight of chocolates. If the weight is less than 1 gram, the defected box is box 1, if the weight is less than 2 grams, the defected box is box 2 and so on.
