• Question 2 of 5 2. Question Regarding thermobaric weapons, consider the following statements: They use the atmosphere’s oxygen to fuel the explosion, creating a powerful blast. These weapons are specifically banned under the Hague Conventions. They are most effective in open fields with large target areas. How many of the above statements is/are correct? a) Only one b) Only two c) All three d) None Correct Solution: a) Statement 1 is correct. Thermobaric weapons use the oxygen from the atmosphere to fuel an explosion, resulting in a high-temperature blast.

• Question 5 of 5 5. Question The respective ratio between the speed of a car, a train, and a bus is 4 : 10 : 6.The average speed of the car , the bus and the train is 72 km/hr together. What is the average speed of the car and the train together? a) 75.6 km/h b) 82 km/h c) 72 km/h d) 67 km/h Correct Answer: Option (a) Explanation: Let speed of the car, the train, and the bus be 4a Km/hr , 10a Km/hr and 6a Km/hr respectively Given: total speed = (72 × 3) Km/hr = 216 Km/hr ⇒4a + 10a + 6a = 216 ⇒20a = 216 ⇒ a = 10.8 Km/hr ⇒ speed of car = 4 × 10.8 = 43.2 Km/hr And, speed of train = 10 × 10.8 = 108 Km/hr ⇒ their average speed = (43.2 + 108) / 2 = 75.6 Km/hr Hence, option (a) is the correct answer. Incorrect Answer: Option (a) Explanation: Let speed of the car, the train, and the bus be 4a Km/hr , 10a Km/hr and 6a Km/hr respectively Given: total speed = (72 × 3) Km/hr = 216 Km/hr ⇒4a + 10a + 6a = 216 ⇒20a = 216 ⇒ a = 10.8 Km/hr ⇒ speed of car = 4 × 10.8 = 43.2 Km/hr And, speed of train = 10 × 10.8 = 108 Km/hr ⇒ their average speed = (43.2 + 108) / 2 = 75.6 Km/hr Hence, option (a) is the correct answer.
#### 5. Question
The respective ratio between the speed of a car, a train, and a bus is 4 : 10 : 6.The average speed of the car , the bus and the train is 72 km/hr together. What is the average speed of the car and the train together?
• a) 75.6 km/h
• b) 82 km/h
• c) 72 km/h
• d) 67 km/h
Answer: Option (a)
Explanation:
Let speed of the car, the train, and the bus be 4a Km/hr , 10a Km/hr and 6a Km/hr respectively
total speed = (72 × 3) Km/hr = 216 Km/hr
⇒4a + 10a + 6a = 216
⇒20a = 216
⇒ a = 10.8 Km/hr
⇒ speed of car = 4 × 10.8 = 43.2 Km/hr
And, speed of train = 10 × 10.8 = 108 Km/hr
⇒ their average speed = (43.2 + 108) / 2 = 75.6 Km/hr Hence, option (a) is the correct answer.
Answer: Option (a)
Explanation:
Let speed of the car, the train, and the bus be 4a Km/hr , 10a Km/hr and 6a Km/hr respectively
total speed = (72 × 3) Km/hr = 216 Km/hr
⇒4a + 10a + 6a = 216
⇒20a = 216
⇒ a = 10.8 Km/hr
⇒ speed of car = 4 × 10.8 = 43.2 Km/hr
And, speed of train = 10 × 10.8 = 108 Km/hr
⇒ their average speed = (43.2 + 108) / 2 = 75.6 Km/hr Hence, option (a) is the correct answer.
