- A) -2
- B) 2
- C) -5
- D) 4
👉 Touch to Show Answer & Explanation

- C) 24 / 63
- D) 18 / 35
👉 Touch to Show Answer & Explanation
Correct Answer: B) 24 / 93
Explanation: Harmonizing ratios: a : b : c = (2 × 4) : (3 × 4) : (3 × 5) = 8 : 12 : 15. Numerator: 3(8) + 2(12) = 24 + 24 = 48. Denominator: 4(12) + 3(15) = 48 + 45 = 93. Ratio = 48/93 (or 24/46.5).

Explanation: The middle point between Q and R is 51. Thus, the four consecutive even numbers are 48, 50, 52, and 54. Product of P(48) and S(54) = 48 × 54 = 2592.
24. A boat goes 32 km downstream and 14 km upstream in 6 hours. If the speed of the stream is 2 km/h, what is the boat's speed in still water?
- A) 6 km/h
- B) 8 km/h
- C) 10 km/h
- D) 12 km/h
👉 Touch to Show Answer & Explanation
Correct Answer: B) 8 km/h
Explanation: Equation: 32 / (v + 2) + 14 / (v - 2) = 6. Substituting v = 8 km/h satisfies: 32 / 10 + 14 / 6 = 3.2 + 2.33... (simplifying 6v² - 46v + 12 = 0 yields (3v - 1)(v - 8) = 0, so v = 8 km/h).
