Explanation

A + B + C + D + E = 40 × 5 = 200

A + B = 35 × 2 = 70

C + D = 42 × 2 = 84

Therefore,

E = (A + B + C + D + E) - (A + B + C + D)

E = 200 - 70 - 84

E = 46 years

Explanation

Step 1: Multiply the number of students in each class by their pass percentage

- Class 1: 10 students × 20% = 2 passed  

- Class 2: 20 students × 30% = 6 passed  

- Class 3: 30 students × 60% = 18 passed  

- Class 4: 40 students × 100% = 40 passed  

Step 2: Add total passed students and total students

- Total passed = 2 + 6 + 18 + 40 = 66  

- Total students = 10 + 20 + 30 + 40 = 100

Step 3: Calculate the overall percentage

Pass % = (66 / 100) × 100 = 66%
