Explanation
The jogger is running at a speed of 9 kmph, which is slower than the train's speed of 45 kmph. The train is 120 meters long and it needs to cover this distance to pass the jogger. The relative speed between the train and the jogger is the difference between their speeds, which is 45 - 9 = 36 kmph. To convert this speed to meters per second, we divide it by 3.6, giving us 10 m/s. The time taken for the train to cover the distance of 120 meters at a speed of 10 m/s is 120/10 = 12 seconds. Therefore, the train will pass the jogger in 12 seconds.

Explanation
Reena took a loan of Rs. 1200 with simple interest for 6 years. This is because the interest paid at the end of the loan period is Rs. 432, which is equal to the rate of interest multiplied by the principal amount and the time period. Therefore, the rate of interest is 6.

Explanation
The first student secured 42 marks and the second student secured 33 marks. The first student's marks is 9 marks more than the second student's marks. Additionally, the first student's marks is 56% of the sum of their marks. This means that if we add the second student's marks to 56% of the sum of their marks, we would get the first student's marks. Therefore, 33 + 56% of (33 + 42) equals 42, which confirms that the first student secured 42 marks and the second student secured 33 marks.

Explanation
In April 2001, Wednesday fell on the 4th, 11th, 18th, and 25th.

Explanation
When the father says "I was as old as you are at the present at the time of your birth," it means that the age difference between the father and the son is the same as the son's current age. Since the father is currently 38 years old, the son's age is 38 - 0 = 38 years. However, the question asks for the son's age five years back, so we subtract 5 from the son's current age to get 38 - 5 = 33 years. Therefore, the son's age five years back was 33 years.

Explanation
The area of the park is given by the product of its length and width, which is 60 m * 40 m = 2400 sq. m. Since the area of the lawn is 2109 sq. m, the area covered by the crossroads must be 2400 sq. m - 2109 sq. m = 291 sq. m. Since the crossroads are rectangular, the width of the road is equal to the width of the crossroads. Therefore, the width of the road is 291 sq. m / 60 m = 4.85 m, which is closest to 3 m.

Explanation
The word "LOGARITHMS" has 10 letters. To form a 4-letter word without repetition, we need to select 4 letters out of these 10. This can be done in 10P4 ways, which is equal to 10! / (10-4)! = 10! / 6! = 10 x 9 x 8 x 7 = 5040. Therefore, there are 5040 4-letter words that can be formed.

Explanation
The word "quiescent" means being in a state of quietness or inactivity. The word "active" is the exact opposite of "quiescent" as it refers to being engaged in physical or mental activity. Therefore, "active" is the correct answer.

Explanation
Physical database design and definition require a specific knowledge of a DBMS because it involves the implementation of the logical database design into the physical storage structures and configuration settings of the DBMS. This includes determining the appropriate data types, indexing strategies, partitioning schemes, and other performance optimization techniques specific to the DBMS being used. It also involves defining the physical storage locations and structures for the database files, such as tables, indexes, and views. Without knowledge of the specific DBMS, it would be difficult to effectively design and define the physical aspects of the database.
