Answer 1. (E) None of these

Explanation:

C5, Total passenger = 80, Children = 12, Adult passenger = 80 − 12 = 68

Female Adult passenger = 68/ 17 × 9 = 36

C7, Total passenger = 80, Children = 10, Adult passenger = 80 − 10 = 70

Female Adult passenger = 70/7 × 4 = 40

Difference = 40 − 36 = 4

 

Answer 2. (B) 5 : 4

Explanation:

C6, Total passenger = 80, Children = 15, Adult passenger = 80 − 15 = 65

Male Adult passenger = 65/ 13 × 8 = 40

C4, Total passenger = 80, Children = 16, Adult passenger = 80 − 16 = 64

Female Adult passenger = 64/ 2 × 1 = 32

Ratio = 40 : 32 = 5 : 4

 

Answer 3. (C) 15

Explanation:

C2, Total passenger = 80, Children = 20, Adult passenger = 80 − 20 = 60

Male Adult passenger = 60/ 5 × 2 = 24

Male adult passenger in C2 on Wednesday = 24 × 125% = 30

Total Adult passenger = 30/ 6 × 13 = 65

Children = 80 − 65 = 15

 

Answer 4. (A) 30.6

Explanation:

C1, Total passenger = 80, Children = 15, Adult passenger = 80 − 15 = 65

Male Adult passenger = 65/ 13 × 7 = 35

C3, Total passenger = 80, Children = 8, Adult passenger = 80 − 8 = 72

Male Adult passenger = 72/ 8 × 3 = 27

C7, Total passenger = 80, Children = 10, Adult passenger = 80 − 10 = 70

Male Adult passenger = 70/ 10 × 3 = 30

Average = (35 + 27 + 30)/ 3 = 30.6

 

Answer 5. (C) 25%

Explanation:

% more = (20 – 16)/ 16 × 100 = 25%
