Solutions:
1. B) From given graph:
The number of computers manufactured by Company B = 13 Lakhs
The number of computers manufactured by all the companies together = 84 Lakhs
Required percentage = 13/84 × 100 = 15.47%

2. E) From given graph:
The number of computers manufactured by Company D = 24 Lakhs
The number of computers manufactured by Company E = 30 Lakhs
Required percentage = 24/34 × 100 = 80%

3. A) From the given graph:
The number of computers sold by Company B = 15
The number of computers manufactured by Company B = 13
Required percentage = 13/15 × 100
= 86.66 %

4. C) From given graph:
Number of computers manufactured by all the companies together = 84 Lakhs
We know, average computer manufactured = (Total computers manufactured)/(Total number of companies) = 84/5 Lakhs = 16.8 Lakhs
Also, number of computers sold by all the companies together = 69 Lakhs
We know, average computer sold = (Total computers manufactured)/(Total number of companies) = 69/5 Lakhs = 13.8 Lakhs
Required difference = (16.8 – 13.8) Lakhs = 300000

5. D) From given graph:
Number of computers manufactured by company A = 10 Lakhs
Number of computers manufactured by company C = 7 Lakhs
Number of computers sold by Company A = 9 Lakhs
And, number of computers sold by Company C = 5 Lakhs
Required ratio = (10 + 7)/(9 + 5) = 17 : 14

6. D) The actual production of A type Bike in 2005 = 36 thousands
The actual production of B type Bike in 2005 = 40 thousands
Required Percentage = (36/40) × 100 = 90%

7. A) Actual production of B type Bike in 2006 = 20 thousands
Targeted production of E type Bike in 2005 = 41 thousands
Difference between the actual production of B type Bike in 2006 and the targeted production of E type Bike in 2005 = (41 – 20) thousands
= 21 thousands = 21000

8. E)

Clearly, Percentage of actual production to targeted production of C type of bikes is highest in 2006. 

9. C) We know that, average = sum of all quantities/number of quantities
Average actual production of D-type Bike over the given years = (17 + 22 + 34 + 17 + 24 + 26)/6 thousands
= 140/6 = 23.33 thousand
Clearly, the average is close to 24 thousand. Thus, in year 2007, the actual production of D-type Bike was closest to the average actual production of D-type Bike over the given years.
