Correct Answer: A
Moderate damage is the correct factual response to “The wind speed between 105-136 km/h normally results in”.
Q45.If the angle of elevation of a tower from a distance of 100 meters from its foot is 60°then the height of the tower is
Correct Answer: B
If the angle of elevation of a tower from a distance of 100 meters from its foot is 60°then the height of the tower is 100 \u221a3m.
Q46.Two trains are running in opposite directions with speeds of 62 km/h and 40 km/h respectively. If the length of one train is 260 m, and they cross each other in 18 seconds, then what is the length of the other train?
Correct Answer: B
250 m is the correct factual response to “Two trains are running in opposite directions with speeds of 62 km/h and 40 km/h respectively. If the length of one train is 260 m, and they cross each other in 18 seconds, then what is the length of the other train”.
Q47.A man takes 6 hours 15 minutes in walking a distance and riding back to starting place . He could walk both ways in 7 hours 45 minutes . The time taken by him to ride back both ways
Correct Answer: B
4 hours and 45 minutes is the correct factual response to “A man takes 6 hours 15 minutes in walking a distance and riding back to starting place. He could walk both ways in 7 hours 45 minutes. The time taken by him to ride back both ways”.
Q48.If the angle of elevation of a tower from a distance of 100 meters from its foot is 60 ° then the height of the tower is:
Correct Answer: A
100 √3 m is the correct factual response to “If the angle of elevation of a tower from a distance of 100 meters from its foot is 60 ° then the height of the tower is:”.
Q49.A horse runs around a ground twice and covers a distance of 8km, one side of square ground is:
Correct Answer: D
If the horse runs around the square ground twice and covers 8 km, one round equals 4 km. A square has four equal sides, so each side is 4 ÷ 4 = 1 km.
Q50.A train left a station at 8:35a.m. and arrived at its destination at 3:12 p.m. How long did the Journey take?
Correct Answer: C
From 8:35 a.m. to 3:12 p.m. is 6 hours and 37 minutes (8:35→2:35 is 6 hours, then 2:35→3:12 is 37 more minutes).
Q51.The angle of depression of a point situated at a distance of 70 m from the base of the tower is 60 The height of tower is;
Correct Answer: A
Height = distance × tan(60°) = 70 × √3 = 70√3 m.
Q52.The distance between two trains is 300 km. One train travels at 60 km/h and the other at 90 km/h toward each other. After how much time will they meet?
Correct Answer: B
Since trains travel toward each other, relative speed = 60 + 90 = 150 km/h. Time = Distance / Relative Speed = 300 / 150 = 2 hours.
Q53.A person travels 80 km north and 60 km west. How far is he from starting point?
Correct Answer: B
Form a right-angled triangle. Hypotenuse = sqrt(80^2 + 60^2) = sqrt(6400 + 3600) = sqrt(10000) = 100 km.
Q54.A train covers 150 km in 3 hours. How much distance in 8 hours?
Correct Answer: C
Speed of train = Distance / Time = 150 / 3 = 50 km/h. Distance in 8 hours = Speed * Time = 50 * 8 = 400 km.
Q55.A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train?
Correct Answer: D
Speed = 60 * (5/18) = 50/3 m/s. Length = Speed * Time = (50/3) m/s * 9 s = 150 meters.
Q56.If a person is traveling 440 km at an average speed, approximately how much time will it take to cover the distance in 2025?
Correct Answer: C
Assuming a typical highway long-distance speed of around 73-75 km/h: Time = Distance / Speed = 440 / 73.3 ≈ 6 hours.
Q57.A and B work 7 hours/day. A completes a task in 6 days, B in 8 days. In how many days will they complete it together working 8 hours/day?
Correct Answer: B
A works 42 total hours, B works 56. Work rates per hour: A=1/42, B=1/56. Combined rate = 1/42 + 1/56 = 7/168 = 1/24. Working 8 hours/day, their daily output is 8 * 1/24 = 1/3. Total days = 3.
Q58.A train covers 240 km. If its speed is increased by 4 km/h, it takes 0.5 hours less. What is the original speed?
Correct Answer: B
Equation: 240/x - 240/(x+4) = 0.5. Simplifying: x² + 4x - 1920 = 0. Factoring: (x - 40)(x + 48) = 0. Since speed must be positive, x = 40 km/h.
Q59.If 6 men can dig a hole in 8 hours, how long will 4 men take to dig the same hole?
Correct Answer: A
Total work = 6 men * 8 hours = 48 man-hours. For 4 men: 48 man-hours / 4 men = 12 hours.
Q60.If A and B can do a work in 18 days, A and C in 12 days, and B and C in 9 days, how many days will B alone take?
Correct Answer: C
Rates: A+B=1/18, A+C=1/12, B+C=1/9. (A+B)+(B+C)-(A+C) = 2B = 1/18 + 1/9 - 1/12 = 2/36 + 4/36 - 3/36 = 3/36 = 1/12. Since 2B = 1/12, B's rate = 1/24. B alone takes 24 days.
