Analysis:
To find the number of students in the elective with the lowest registration, we need to make some assumptions and use the given information.

Assumptions:
1. All students are required to take the mandatory course.
2. Each student can only register for two electives.
3. There are no students who have registered for more than the required number of courses.

Calculating the number of students in the elective with the lowest registration:

Step 1: Calculate the total number of students in the final semester.
- The total number of students registered for the mandatory course is 70.

Step 2: Calculate the total number of students registered for electives.
- The total number of students registered for electives is 45 + 55 = 100.

Step 3: Find the number of students in each elective course.
- Since each student can only register for two electives, we divide the total number of students registered for electives by 2 to get the number of students in each elective course.
- The number of students in each elective course is 100 / 2 = 50.

Step 4: Find the number of students in the elective with the lowest registration.
- Since we have three elective courses, we need to compare the number of students in each elective course to find the lowest registration.
- The number of students in the elective with the lowest registration is 50, since all elective courses have an equal number of students.

Conclusion:
The number of students in the elective with the lowest registration is 50.

There were seven elective courses - El to E7 - running in a specific term in a college. Each of the 300 students enrolled had chosen just one elective from among these seven. However, before the start of the term, E7 was withdrawn as the instructor concerned had left the college. The students who had opted for E7 were allowed to join any of the remaining electives, Also, the students who had chosen other electives were given one chance to change their choice. The table below captures the movement of the students from one elective to another during this process. Movement from one elective to the same elective simply means no movement. Some numbers in the table got accidentally erased; however, it is known that these were either 0 or 1. Further, the following are known: Before the change process there were 6 more students in El than in E4, but after the reshuffle, the number of students in E4 was 3 more than that in El. The number of students in E2 increased by 30 after the change process. Before the change process, E4 had 2 more students than E6, while E2 had 10 more students than E3Q.Later, the college imposed a condition that if after the change of electives, the enrollment in any elective (other than E7) dropped to less than 20 students, all the students who had left that course will be required to re­enroll for that elective.Which of the following is a correct sequence of electives in decreasing order of their final enrollments?

Directions: Study the given information and answer the following question.A car servicing company has ten LED boards which are fitted on a wall. Each of them displays the digits from 0-9. They are programmed in such a way that when any car enters the workshop for service, the registration number on the cars number plate will appear on the wall as the digits on the wall-mounted LED boards shall glow to show a 4-digit number. On Monday, 4 cars of different colours, i.e. red, white, black and grey, entered the workshop. Due to faulty software, the only thing that got noted down was the number of times each LED board glowed in total after the 4 cars entered. Hence, the following data was collected.Further, software provided the following data:(1) The registration number of each car has a factor 5.(2) Except the white car, all the other cars have at least three different digits.(3) The registration number of black car has the highest value numerically.(4) The registration number of red car has four different digits, three of which are not present in the registration numbers of any of the other 3 cars.(5) The difference between the registration numbers of red car and grey car has a maximum value of 600 and a minimum value of 500.(6) The registration number of white car is exactly a factor of the registration number of black car.(7) The sum of the digits of registration number of white car is 8.How many of the four cars have a registration number which is a multiple of 3? Key in the correct value. Correct answer is '1'. Can you explain this answer?
