Understanding Credit Enrollment Constraints
This problem involves determining the maximum number of credits a student can take in elective courses, subject to several conditions regarding total credits and required credits for different course types.
Key Enrollment Rules:
- Minimum total credits required: 60
- Maximum total credits allowed: 70
- Mandatory Core Courses credits: 15
- Mandatory Project credits: 20
- Minimum Specialization Courses credits: 10
- Elective Courses credits: Need to find the maximum possible value.
Calculating Maximum Elective Credits
Let $C_{\text{total}}$ represent the total credits enrolled by a student. Let $C_{\text{core}}$, $C_{\text{project}}$, $C_{\text{spec}}$, and $C_{\text{elective}}$ represent the credits for core courses, project, specialization courses, and elective courses, respectively.
The sum of credits must satisfy:
$C_{\text{total}} = C_{\text{core}} + C_{\text{project}} + C_{\text{spec}} + C_{\text{elective}}$
Plugging in the known fixed values:
$C_{\text{total}} = 15 + 20 + C_{\text{spec}} + C_{\text{elective}}$
$C_{\text{total}} = 35 + C_{\text{spec}} + C_{\text{elective}}$
To find the maximum value for $C_{\text{elective}}$, we rearrange the formula:
$C_{\text{elective}} = C_{\text{total}} - 35 - C_{\text{spec}}$
To maximize $C_{\text{elective}}$, we should choose the highest possible value for $C_{\text{total}}$ and the lowest possible value for $C_{\text{spec}}$ that satisfy the constraints.
- The maximum allowed $C_{\text{total}}$ is 70.
- The minimum required $C_{\text{spec}}$ is 10.
Final Calculation and Verification
Using the maximum $C_{\text{total}}$ and minimum $C_{\text{spec}}$:
Maximum $C_{\text{elective}} = 70 - 35 - 10$
Maximum $C_{\text{elective}} = 35 - 10$
Maximum $C_{\text{elective}} = 25$
Verification: If a student enrolls for 25 credits of electives, along with the compulsory 15 credits of core courses, 20 credits of project, and the minimum 10 credits of specialization, the total credits are $15 + 20 + 10 + 25 = 70$. This total fits within the allowed range of 60 to 70 credits.

Two design consultants, P and Q, started working from 8 AM for a client. The client budgeted a total of USD 3000 for the consultants. P stopped working when the hour hand moved by 210 degrees on the clock. Q stopped working when the hour hand moved by 240 degrees. P took two tea breaks of 15 minutes each during her shift, but took no lunch break. Q took only one lunch break for 20 minutes, but no tea breaks. The market rate for consultants is USD 200 per hour and breaks are not paid. After paying the consultants, the client shall have USD_remaining in the budget.
