On the basis of given graph in question ,
Year 1976 , Total number of job seekers = 3300
Number of Graduate and senior secondary job seekers = 1800
∴ Number of Matriculate job seekers = 3300 – 1800 = 1500
Year 1977 , Total number of job seekers = 4000
Number of Graduate and senior secondary job seekers = 2200
∴ Number of Matriculate job seekers =
4000 – 2200 = 1800 ⇒ maximumCorrect Option: D

According to given bar graph , we have
→ Year 1973 , Number of jobseekers = 1625
→ Year 1977 , Number of jobseekers = 4000
Required difference = Number of jobseekers in 1977  Number of jobseekers in 1973Correct Option: C
According to given bar graph , we have
→ Year 1973 , Number of jobseekers = 1625
→ Year 1977 , Number of jobseekers = 4000
Required difference = Number of jobseekers in 1977  Number of jobseekers in 1973

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
