United India Insurance AO Exam 2013 Question Paper

People who read only English = $$a = 650$$

Similarly, $$c = 550$$

$$g = 450$$

People who read all three newspapers = $$e = 100$$

Also, people who read English and Hindi = $$b + e = 200$$

=> $$b = 200 - 100 = 100$$

Similarly, $$d = 200$$

$$f = 300$$

Number of members reading English as well as Marathi newspaper = $$d + e$$

= $$200 + 100 = 300$$

Number of members reading English as well as Hindi newspaper = $$b + e$$

= $$100 + 100 = 200$$

=> Required difference = $$300 - 200 = 100$$

People who read only English = $$a = 650$$

Similarly, $$c = 550$$

$$g = 450$$

People who read all three newspapers = $$e = 100$$

Also, people who read English and Hindi = $$b + e = 200$$

=> $$b = 200 - 100 = 100$$

Similarly, $$d = 200$$

$$f = 300$$

Members who read at least two newspapers = $$b + d + e + f$$

= $$100 + 200 + 100 + 300 = 700$$

People who read only English = $$a = 650$$

Similarly, $$c = 550$$

$$g = 450$$

People who read all three newspapers = $$e = 100$$

Also, people who read English and Hindi = $$b + e = 200$$

=> $$b = 200 - 100 = 100$$

Similarly, $$d = 200$$

$$f = 300$$

Members who read Hindi newspaper = $$b + c + e + f$$

= $$100 + 550 + 100 + 300 = 1050$$

People who read only English = $$a = 650$$

Similarly, $$c = 550$$

$$g = 450$$

People who read all three newspapers = $$e = 100$$

Also, people who read English and Hindi = $$b + e = 200$$

=> $$b = 200 - 100 = 100$$

Similarly, $$d = 200$$

$$f = 300$$

Members who read only 1 newspaper = $$a + c + g$$

= $$650 + 550 + 450 = 1650$$

People who read only English = $$a = 650$$

Similarly, $$c = 550$$

$$g = 450$$

People who read all three newspapers = $$e = 100$$

Also, people who read English and Hindi = $$b + e = 200$$

=> $$b = 200 - 100 = 100$$

Similarly, $$d = 200$$

$$f = 300$$

Number of people who do not read any newspaper = $$h$$

Here, $$a + b + c + d + e + f + g + h = 2800$$

=> $$650 + 100 + 550 + 200 + 100 + 300 + 450 + h = 2800$$

=> $$h = 2800 - 2350 = 450$$

Number of computers manufactured by companies A and C together = 10 + 7.5 = 17.5

Number of computers sold by companies A and C together = 7.5 + 5 = 12.5

=> Required ratio = 17.5 : 12.5 

= 175 : 125 = 7 : 5

Total number of computers manufactured by all the companies together

= 10 + 15 + 7.5 + 22.5 + 30 = 85 lakhs

Total number of computers sold by all the companies together 

= 7.5 + 12.5 + 5 + 17.5 + 25 = 67.5 lakhs

Difference = 85 - 67.5 = 17.5 lakhs

=> Required average = $$\frac{17,50,000}{5} = 3,50,000$$

Number of computers sold by company B = 12.5

Number of computers manufactured by company B = 15

=> Required % = $$\frac{12.5}{15} \times 100$$

= $$\frac{250}{3} = 83.33 \%$$

Number of computers manufactured by company D = 22.5

Number of computers manufactured by company E = 30

=> Required % = $$\frac{22.5}{30} \times 100$$

= $$7.5 \times 10 = 75 \%$$

Number of computers manufactured by company B (in lakhs) = 15

Number of computers manufactured by all the companies together (in lakhs)

= 10 + 15 + 7.5 + 22.5 + 30 = 85

=> Required % = $$\frac{15}{85} \times 100$$

= $$17.64 \% \approx 18 \%$$
