From the given bar diagram , we see
The total production of table fans from Monday to Wednesday = 260 + 540 + 360 = 1160
The total production of table fans from Thursday to Saturday = 120 + 200 + 320 = 640
Required ratio = The total production of table fans from Monday to Wednesday : The total production of table fans from Thursday to SaturdayCorrect Option: C
From the given bar diagram , we see
The total production of table fans from Monday to Wednesday = 260 + 540 + 360 = 1160
The total production of table fans from Thursday to Saturday = 120 + 200 + 320 = 640
Required ratio = The total production of table fans from Monday to Wednesday : The total production of table fans from Thursday to Saturday
∴ Required ratio = 1160 : 640 = 29 : 16

On the basis of given graph in question ,
Sum of production of table fans = 260 + 540 + 360 + 120 + 200 + 320 = 1800
Number of days = 6Required average = Sum of production of table fans Number of days Required average = 260 + 540 + 360 + 120 + 200 + 320 6
Correct Option: C
On the basis of given graph in question ,
Sum of production of table fans = 260 + 540 + 360 + 120 + 200 + 320 = 1800
Number of days = 6Required average = Sum of production of table fans Number of days Required average = 260 + 540 + 360 + 120 + 200 + 320 6 Required average = 1800 = 300 6
 The maximum production exceeds the minimum production by :

As per the given bar graph , we see
Maximum production = 540
Minimum production = 120
Required difference = Maximum production  Minimum productionCorrect Option: B
As per the given bar graph , we see
Maximum production = 540
Minimum production = 120
Required difference = Maximum production  Minimum production
Required difference = 540 – 120 = 420

On the basis of given graph in question ,
The number of accidents in May = 35
The number of accidents in June = 27
Decrease = 35  27 = 8Required percent = Decrease × 100 The number of accidents in May Required percent = 8 × 100 = 160 35 7
Correct Option: C
On the basis of given graph in question ,
The number of accidents in May = 35
The number of accidents in June = 27
Decrease = 35  27 = 8Required percent = Decrease × 100 The number of accidents in May Required percent = 8 × 100 = 160 35 7 Required percent = 22 6 % 7

According to given bar graph , we have
Total number of accidents = 25 + 19 + 30 + 43 + 35 + 27 = 179
Number of months = 6Average Number of accidents = Total number of accidents = 29.83 Number of months Average Number of accidents = 179 = 29.83 6
Number of accidents in April = 43Correct Option: A
According to given bar graph , we have
Total number of accidents = 25 + 19 + 30 + 43 + 35 + 27 = 179
Number of months = 6Average Number of accidents = Total number of accidents = 29.83 Number of months Average Number of accidents = 179 = 29.83 6
Number of accidents in April = 43
∴ Required answer = 43 – 29.83 = 13.17
