- A.
Both I and II are necessary to answer
- B.
I alone sufficient while II alone not sufficient to answer
- C.
Both I and II are not sufficient to answer
- D.
II alone sufficient while I alone not sufficient to answer
Correct Answer
A. Both I and II are necessary to answerExplanation
Both I and II are necessary to answer the question.
In order to determine the length of the running train crossing another train, we need to know the relative speed of the two trains (I) and the time it takes for them to cross each other (II). The relative speed gives us the rate at which the two trains are approaching each other, and the time it takes for them to cross gives us the distance they cover. By multiplying the relative speed by the time taken, we can calculate the length of the running train. Therefore, both I and II are necessary to answer the question.Rate this question:

The pattern in the given sequence is that each letter is shifted forward by one position in the alphabet. Starting from S, the first letter in the sequence, we shift by one position to get T. Continuing this pattern, we shift by one position from each subsequent letter to get the next letter in the sequence. Therefore, starting from U, we shift by one position to get V, then shift from G to get H, and so on. Applying this pattern, the missing letter after UGH would be V, which is followed by WKL in the sequence.Rate this question:

Correct Answer
A. Neither I nor II followsExplanation
The given statements state that in a one day cricket match, the total runs made by a team were 200 and out of these, 160 runs were made by spinners. However, we cannot conclude that 80% of the team consists of spinners based on this information alone. It is possible that the spinners made a majority of the runs, but it does not necessarily mean they make up 80% of the team. Similarly, we cannot conclude that the opening batsmen were spinners as the information does not provide any details about the specific roles of the players. Therefore, neither conclusion I nor II follows.Rate this question:

- A.
Dotage
- B.
Senility
- C.
Imbecility
- D.
Superannuation
Correct Answer
A. DotageExplanation
Dotage is the correct answer because it refers to extreme old age when a person's mental faculties, such as memory and judgment, become impaired. It is a state in which a person behaves foolishly or childishly due to old age. Senility refers to the loss of mental faculties in old age, but it does not specifically imply foolish behavior. Imbecility refers to a state of extreme stupidity or foolishness, but it does not necessarily imply old age. Superannuation refers to the act of retiring from work due to old age, but it does not capture the concept of behaving like a fool.Rate this question:

How many times do the hands of a clock coincide in a day?
- A.
20
- B.
21
- C.
22
- D.
23
Correct Answer
C. 22Explanation
The hands of a clock coincide when they overlap or are in the same position. In a 12-hour clock, the hour hand and minute hand coincide 11 times. This is because the hour hand completes a full revolution 12 times in 12 hours, while the minute hand completes a full revolution once every hour. However, the first coincidence occurs at 12 o'clock, so we need to subtract 1 from the total. Additionally, the hour and minute hand coincide at 12 o'clock midnight and 12 o'clock noon, making a total of 22 coincidences in a day.Rate this question:

- A.
TUESDAY
- B.
MONDAY
- C.
SATURDAY
- D.
SUNDAY
Correct Answer
A. TUESDAYExplanation
The last day of a century cannot be Tuesday because a century consists of 100 years, and each year has 365 days (except for leap years). Since 365 is not divisible by 7, the days of the week do not align perfectly with the calendar days. Therefore, it is not possible for the last day of a century to be Tuesday.Rate this question:

A farmer travelled a distance of 61 km in 9 hours. He travelled partly on foot @ 4 km/hr and partly on bicycle @ 9 km/hr. The distance travelled on foot is:
- A.
14 KM
- B.
15 KM
- C.
16 KM
- D.
17 KM
Correct Answer
C. 16 KMExplanation
The farmer traveled a total distance of 61 km in 9 hours. Let's assume he traveled x km on foot and (61 - x) km on a bicycle. The time taken to travel on foot can be calculated as x/4 hours, and the time taken to travel on a bicycle can be calculated as (61 - x)/9 hours. Since the total time taken is 9 hours, we can set up the equation x/4 + (61 - x)/9 = 9. Solving this equation, we find that x = 16 km. Therefore, the distance traveled on foot is 16 km.Rate this question:

3 pumps, working 8 hours a day, can empty a tank in 2 days. How many hours a day must 4 pumps work to empty the tank in 1 day?
- A.
9
- B.
10
- C.
11
- D.
12
Correct Answer
D. 12Explanation
If 3 pumps working for 8 hours a day can empty the tank in 2 days, it means that each pump can empty 1/6th of the tank in 1 day. To empty the tank in 1 day, we need to increase the number of pumps to 4. Since each pump can empty 1/6th of the tank in 1 day, 4 pumps can empty 4/6th or 2/3rd of the tank in 1 day. Therefore, the 4 pumps must work for 12 hours a day to empty the tank in 1 day.Rate this question:

The question given below consists of a question followed by three statements. You have to study the question and the statements and decide which of the statement(s) is/are necessary to answer the question. What is the speed of the train?I. The train crosses a signal pole in 18 seconds.II. The train crosses a platform of equal length in 36 seconds. III. Length of the train is 330 metres.
- A.
I and II only
- B.
II and III only
- C.
I and III only
- D.
III and either I or II only
Correct Answer
D. III and either I or II onlyExplanation
To determine the speed of the train, we need to know the time it takes for the train to cross a certain distance. Statement III tells us the length of the train, which is necessary information to calculate the speed. Either statement I or II is also necessary because they provide the time it takes for the train to cross a certain distance. Therefore, the correct answer is III and either I or II only.Rate this question:

If one-third of one-fourth of a number is 15, then three-tenth of that number is:
- A.
35
- B.
36
- C.
45
- D.
54
Correct Answer
D. 54Explanation
If one-third of one-fourth of a number is 15, it means that (1/3) * (1/4) * x = 15, where x is the number. Simplifying this equation, we get x = 15 * 12 = 180. Now, we need to find three-tenth of this number, which is (3/10) * 180 = 54. Therefore, the correct answer is 54.Rate this question:

From a point P on a level ground, the angle of elevation of the top tower is 30º. If the tower is 100 m high, the distance of point P from the foot of the tower is:
- A.
173 m
- B.
143 m
- C.
147 m
- D.
153 m
Correct Answer
A. 173 mExplanation
The angle of elevation is the angle formed between the line of sight from the observer to the object and the horizontal ground. In this question, the angle of elevation is given as 30° and the height of the tower is given as 100 m. By using trigonometry, we can determine that the distance from point P to the foot of the tower is equal to the height of the tower divided by the tangent of the angle of elevation. Therefore, the distance of point P from the foot of the tower is 100 m / tan(30°) = 173 m.Rate this question:

A tank is filled by three pipes with uniform flow. The first two pipes operating simultaneously fill the tank in the same time during which the tank is filled by the third pipe alone. The second pipe fills the tank 5 hours faster than the first pipe and 4 hours slower than the third pipe. The time required by the first pipe is:
- A.
6 hours
- B.
10 hours
- C.
15 hours
- D.
30 hours
Correct Answer
C. 15 hoursExplanation
The first pipe fills the tank in 15 hours. This can be determined by setting up a system of equations. Let's assume that the first pipe fills the tank at a rate of x tanks per hour. Since the second pipe fills the tank 5 hours faster than the first pipe, its rate is x + 5 tanks per hour. Similarly, the third pipe fills the tank 4 hours faster than the second pipe, so its rate is x + 5 + 4 = x + 9 tanks per hour.
The first two pipes fill the tank in the same time as the third pipe alone, so we can set up the equation:
15x + 15(x + 5) = 15(x + 9)
Simplifying this equation, we get:
15x + 15x + 75 = 15x + 135
30x + 75 = 15x + 135
15x = 60
x = 4
Therefore, the first pipe fills the tank in 15 hours.Rate this question:

A and B take part in 100 m race. A runs at 5 kmph. A gives B a start of 8 m and still beats him by 8 seconds. The speed of B is:A and B take part in 100 m race. A runs at 5 kmph. A gives B a start of 8 m and still beats him by 8 seconds. The speed of B is:
- A.
4.14 kmph
- B.
5.15 kmph
- C.
4.25 kmph
- D.
4.4 kmph
Correct Answer
A. 4.14 kmphExplanation
To find the speed of B, we need to first calculate the time taken by A to complete the race. Since A runs at 5 kmph, we can convert this to m/s by multiplying by 5/18. Therefore, the speed of A is (5*5/18) m/s.
Now, let's calculate the time taken by A to complete the race. We know that time = distance/speed. The distance covered by A is 100m - 8m (the head start given to B) = 92m.
So, the time taken by A to complete the race is 92/((5*5/18)) = 33.12 seconds.
Since A beats B by 8 seconds, the time taken by B to complete the race is 33.12 + 8 = 41.12 seconds.
Now, let's calculate the speed of B. We know that speed = distance/time. The distance covered by B is 100m.
So, the speed of B is 100/41.12 = 2.43 m/s.
To convert this to kmph, we multiply by 18/5. Therefore, the speed of B is (2.43*18/5) kmph which is approximately 4.14 kmph.Rate this question:
