A box contains a mixture of black and white socks. How many socks must you remove, without looking, to ensure that you have a matching pair?

You need to remove only three socks. The worst-case scenario is that you remove two black socks and then the next sock you remove will guarantee a matching pair (either black or white).
If five skilled archers can shoot five targets in five minutes, how many archers would be necessary to shoot 100 targets in 100 minutes?
See Answer
If five skilled archers can shoot five targets in five minutes, it implies that each archer can shoot one target in five minutes. Therefore, to shoot 100 targets in 100 minutes, you would still only need five archers. Each archer can maintain the same rate of shooting, resulting in a total of 100 targets being hit.
In a distant land, there are three magical rings. The second ring weighs twice as much as the first ring, and the third ring weighs three times as much as the second ring. Together, the three rings weigh 36 grams. What is the weight of each individual ring?
See Answer
Let's solve the riddle together. Let's represent the weight of the first ring as "x" grams. According to the riddle, the second ring weighs twice as much as the first ring, so its weight is 2x grams. Similarly, the third ring weighs three times as much as the second ring, so its weight is 3 * (2x) = 6x grams. The total weight of the three rings is given as 36 grams: x + 2x + 6x = 36 Combining like terms: 9x = 36 Dividing both sides by 9: x = 4 So, the weight of the first ring is 4 grams, the second ring weighs twice as much, which is 2 * 4 = 8 grams, and the third ring weighs three times as much as the second ring, which is 3 * 8 = 24 grams.

A goat is purchased by a man for $60, then sold for $70. Later, the man repurchases the goat for $80 and subsequently sells it once more for $90. How much profit did he make?
See Answer
The man made a profit of $20. He bought the goat for $60 and sold it for $70, making a profit of $10. Then he bought it back for $80 and sold it for $90, making another profit of $10. In total, the profit is $10 + $10 = $20.
Which combination of three positive numbers produces equal results when multiplied and added together?

I am a mysterious three-digit number. The difference between my tens digit and ones digit is 5, while the difference between my hundreds digit and tens digit is 8. What number am I?
See Answer
Let's solve the riddle together. We know that the difference between the tens digit and ones digit is 5. Therefore, the possible pairs of digits that satisfy this condition are (6, 1), (7, 2), (8, 3), and (9, 4). Next, we know that the difference between the hundreds digit and tens digit is 8. This means that the tens digit must be greater than the hundreds digit by 8. Considering the possible pairs we found earlier, only (9, 4) satisfies this condition, as 9 - 8 = 1. Therefore, the number we are looking for is 914.
