**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.
