30 (Correct answer)
40
20
50

Correct answer: 30

Let the son's current age be 's' and the man's current age be 'm'. From the problem, we have m = 3s. In 10 years, the son's age will be s+10 and the man's age will be m+10. At that time, m+10 = 2(s+10). Substitute m = 3s into the second equation: (3s)+10 = 2(s+10). This becomes 3s + 10 = 2s + 20. Subtracting 2s from both sides gives s + 10 = 20, so s = 10. The son's current age is 10. The man's current age is m = 3s = 3(10) = 30.

10
20 (Correct answer)
15
5

Correct answer: 20

From the first equation, a/b = 4, we can express 'a' in terms of 'b': a = 4b. Now, substitute this expression into the second equation: (4b) - 2b = 10. This simplifies to 2b = 10, so b = 5. To find 'a', substitute the value of 'b' back into a = 4b. This gives a = 4(5), so a = 20.

R
S
P
Q (Correct answer)

Correct answer: Q

The statement 'R is heavier than only T' establishes that T is the lightest and R is the second lightest (T < R). The statement 'P is heavier than S but lighter than Q' gives the order S < P < Q. Since R is only heavier than T, the other three boxes (Q, P, S) must all be heavier than R. This combines to give the complete order: T < R < S < P < Q. Therefore, Q is the heaviest.

Question 98: An astronaut on the Moon strikes a rock with a hammer, but their fellow astronaut standing nearby hears nothing. Why is this?

The helmets worn by astronauts block all external sound.
The sound produced is too quiet to be heard from that distance.
The gravitational pull on the Moon is too weak for sound to travel.
Sound requires a medium, like air or water, to travel, and the Moon has no atmosphere. (Correct answer)

Correct answer: Sound requires a medium, like air or water, to travel, and the Moon has no atmosphere.

Sound travels as a wave of vibrations through a medium (solid, liquid, or gas). The Moon is essentially a vacuum with no atmosphere. Without a medium like air for the vibrations to travel through, sound waves cannot propagate, and therefore no sound can be heard.

Question 99: In a town, the ratio of men to women is 5:4. If the total population of the town is 45,000, what is the number of women?

25,000
15,000

The ratio 5:4 means there are 5+4 = 9 parts in total. To find the value of one part, divide the total population by the total number of parts: 45,000 / 9 = 5,000. The number of women corresponds to 4 parts, so multiply the value of one part by 4: 5,000 * 4 = 20,000.
