According to given bar graph , we have
→ Year 1973 , Number of job-seekers = 1625
→ Year 1977 , Number of job-seekers = 4000
Required difference = Number of job-seekers in 1977 - Number of job-seekers in 1973Correct Option: C
According to given bar graph , we have
→ Year 1973 , Number of job-seekers = 1625
→ Year 1977 , Number of job-seekers = 4000
Required difference = Number of job-seekers in 1977 - Number of job-seekers in 1973
∴ Required difference = 4000 – 1625 = 2375

On the basis of given graph in question ,
Number of Graduate job- seekers in 1974 = 525
Total number of Graduate and Senior secondary job- seekers in 1974 = 1050Correct Option: B
On the basis of given graph in question ,
Number of Graduate job- seekers in 1974 = 525
Total number of Graduate and Senior secondary job- seekers in 1974 = 1050
∴ Number of Senior secondary job -seekers in 1974 = 1050 – 525 = 525

From the given bar diagram , we see that one box represents a number of 20 units.
Number of the accidents involving buses = 6 boxes = 6 × 20 = 120 units
Number of the accidents involving tanker lorry = 8 boxes = 8 × 20 = 160 units
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000 unitsCorrect Option: B

As per the given bar diagram , we see that one box represents a number of 20 units.
Number of the accidents involving pedestrians = 2 boxes = 2 × 20 = 40 units
Number of the accidents involving cyclists = 10 boxes = 10 × 20 = 200 units
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000 unitsRequired percentage = 40 + 200 × 100 1000
Correct Option: A

On the basis of given graph in question , we see that one box represents a number of 20 units.
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000 units
In pie chart , complete angle = 360°
∵ 1000 ≡ 360°∴ 100 ≡ 360 × 100 = 36° 1000
Correct Option: D
On the basis of given graph in question , we see that one box represents a number of 20 units.
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000 units
In pie chart , complete angle = 360°
∵ 1000 ≡ 360°∴ 100 ≡ 360 × 100 = 36° 1000
From above clear that this sector represents the accidents involving stationary vehicles .
So , stationary vehicles having in diagram = 5 Boxes = 5 × 20 = 100 units
Hence , required answer is option D .
