1. **Stating the problem:** We are given tables with student scores in various assessment components: TEST 1 (15), GROUP WORK (10), TEST 2 (15), PROJECT (20), SUB TOTAL (60), (A) 50%, TERM EXAM (100), (B) 50%, and OVERALL TOTAL (A+B). 2. **Formulas and rules:** - SUB TOTAL (60) = TEST 1 + GROUP WORK + TEST 2 + PROJECT - (A) 50% = 0.5 \times SUB TOTAL - (B) 50% = 0.5 \times TERM EXAM - OVERALL TOTAL (A+B) = (A) 50% + (B) 50% 3. **Example calculation for the first student in the first table:** - TEST 1 = 11, GROUP WORK = 10, TEST 2 = 8, PROJECT = 12 - SUB TOTAL = 11 + 10 + 8 + 12 = 41 - (A) 50% = 0.5 \times 41 = 20.5 - TERM EXAM = 22 (given) - (B) 50% = 0.5 \times 22 = 11 - OVERALL TOTAL = 20.5 + 11 = 31.5 4. **Filling missing values:** For each student, sum the four components to get SUB TOTAL, multiply by 0.5 for (A), multiply TERM EXAM by 0.5 for (B), then add (A) and (B) for OVERALL TOTAL. 5. **Summary:** Use the formulas above to complete all missing SUB TOTAL, (A), (B), and OVERALL TOTAL values in the tables. This method applies to all tables provided.
