Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr. The faster train passes the slower train in 36 seconds. The length of each train is:
Answer: Option (A) 50 m Explanation: Let the length of each train be x metres. Then, distance covered = 2x metres. Relative speed = (46 - 36) km/hr = 10 x (5 /18)m/sec = 25/9 m/sec 2x/36 = 25/9 2x = 100 x = 50.
Answer: Option (A) 50 m
Explanation:
Let the length of each train be x metres.
Then, distance covered = 2x metres.
Relative speed = (46 – 36) km/hr
= 10 x (5 /18)m/sec
= 25/9 m/sec
2x/36 = 25/9
2x = 100
x = 50.
See lessA train 240 m long passes a pole in 24 seconds. How long will it take to pass a platform 650 m long?
Answer: Option (B) 89 sec Explanation: Speed = (240/24) m/sec = 10 m/sec. Required time = (240 + 650)/10 sec = 89 sec.
Answer: Option (B) 89 sec
See lessExplanation:
Speed = (240/24) m/sec = 10 m/sec.
Required time = (240 + 650)/10 sec = 89 sec.
Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively and they cross each other in 23 seconds. The ratio of their speeds is:
Answer: Option (B) 3 : 2 Explanation: Let the speeds of the two trains be x m/sec and y m/sec respectively. Then, length of the first train = 27x metres, and length of the second train = 17y metres. (27x + 17y) /(x+ y)= 23 27x + 17y = 23x + 23y 4x = 6y x /y= 3/2 .
Answer: Option (B) 3 : 2
See lessExplanation:
Let the speeds of the two trains be x m/sec and y m/sec respectively.
Then, length of the first train = 27x metres,
and length of the second train = 17y metres.
(27x + 17y) /(x+ y)= 23
27x + 17y = 23x + 23y
4x = 6y
x /y= 3/2 .
The length of the bridge, which a train 130 metres long and travelling at 45 km/hr can cross in 30 seconds, is:
Answer: Option (C) 245 m Explanation: Speed = 45 x 5 m/sec = 25 m/sec. 18 2 Time = 30 sec. Let the length of bridge be x metres. Then, 130 + x = 25 30 2 2(130 + x) = 750 x = 245 m.
Answer: Option (C) 245 m
Explanation:
Speed = 45 x 5 m/sec = 25 m/sec.
18 2
Time = 30 sec.
Let the length of bridge be x metres.
Then, 130 + x = 25
30 2
2(130 + x) = 750
x = 245 m.
See lessA train 125 m long passes a man, running at 5 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is:
Answer: Option (B) 50 km/hr Explanation: Speed of the train relative to man = 125 m/sec 10 = 25 m/sec. 2 = 25 x 18 km/hr 2 5 = 45 km/hr. Let the speed of the train be x km/hr. Then, relative speed = (x - 5) km/hr. x - 5 = 45 x = 50 km/hr.
Answer: Option (B) 50 km/hr
Explanation:
Speed of the train relative to man = 125 m/sec
10
= 25 m/sec.
2
= 25 x 18 km/hr
2 5
= 45 km/hr.
Let the speed of the train be x km/hr. Then, relative speed = (x – 5) km/hr.
x – 5 = 45 x = 50 km/hr.
See lessA train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train?
Answer: Option (D) 150 metres Explanation: Speed = 60 x 5 m/sec = 50 m/sec. 18 3 Length of the train = (Speed x Time). Length of the train = 50 x 9 m = 150 m.
Answer: Option (D) 150 metres
Explanation:
Speed = 60 x 5 m/sec = 50 m/sec.
18 3
Length of the train = (Speed x Time).
Length of the train = 50 x 9 m = 150 m.
See lessA train passes a station platform in 36 seconds and a man standing on the platform in 20 seconds. If the speed of the train is 54 km/hr, what is the length of the platform?
Answer: Option B Explanation:Speed = 54 x (5/18) m/sec = 15 m/sec.Length of the train = (15 x 20)m = 300 m. Let the length of the platform be x metres. Then, (x + 300)/36 = 15x + 300 = 540 x = 240 m.
Answer: Option B
Explanation:
Speed = 54 x (5/18) m/sec = 15 m/sec.
Length of the train = (15 x 20)m = 300 m.
Let the length of the platform be x metres.
Then, (x + 300)/36 = 15
x + 300 = 540
x = 240 m.

Correct Answer: (B) Indus Valley civilization Explanation: The Harappan civilization is another name for the Indus Valley civilization. It flourished in the Indus and Saraswati river valleys around 3300 BCE to 1300 BCE. The other options are not directly related to the Harappan civilization: SumeriaRead more
Correct Answer: (B) Indus Valley civilization
Explanation:
- The Harappan civilization is another name for the Indus Valley civilization. It flourished in the Indus and Saraswati river valleys around 3300 BCE to 1300 BCE.
- The other options are not directly related to the Harappan civilization:
- Sumerian civilization existed in Mesopotamia (present-day Iraq, Kuwait, Syria, Turkey) around the same time as the Indus Valley civilization, but they were distinct cultures.
- Vedic civilization refers to a later period in Indian history (1500 BCE to 500 BCE) associated with the development of Vedic literature and the arrival of Indo-European speakers.
- Mesopotamian civilization is a broader term encompassing various cultures that flourished in Mesopotamia, including Sumerians.

Correct Answer: (B) It has its own script
Explanation:
The classification of Indus Valley Civilization as Aryan or Non-Aryan is complex and not solely based on archaeological findings. However, the presence of a distinct, undeciphered script ( Indus Script) distinguishes the Indus Valley Civilization from later Vedic civilization, which is associated with the arrival of Indo-European speakers and the development of the Sanskrit language.
Here’s why the other options are not necessarily indicative of being Non-Aryan:
- (A) Urban Civilization: While the Indus Valley was a prominent urban civilization, there’s no clear link between urbanization and Aryan/Non-Aryan categorization.
- (C) Agricultural Economy: Agriculture was a common feature of many ancient societies, and doesn’t necessarily point towards Aryan or Non-Aryan origins.
- (D) Extended Upto Narmada Valley: The geographical extent doesn’t determine the racial or linguistic identity of a civilization.
