Average number of non-governmental projects handled by company B = 127
Number of Non-Governmental projects handled by company B in 2003 and 2004 is
= 127 × 2
= 254
Number of Governmental projects handled by company B in 2003 and 2004 together
= 130 + 320 - 254
= 450 - 254
= 196

Question 122. Directions (1 - 5): Refer to the graph and answer the given questions:

If the number of projects handled by company A increased by 20% from 2007 to 2008 and by 5% from 2008 to 2009, what was the number of projects handled by company A in 2009?

Discuss Question

Answer: Option A. -> 378
Number of projects handled by company A in 2008

= 360
Number of projects handled by company A in 2009
= 105% of 360
= $$\frac{105\times360}{100}$$
= 378

Question 123. Directions (1 - 2): The graph given below shows the daily income of 50 workers in a factory. Study the graph and answer the questions.

The median wages in the factory is:

Rs. 140
Rs. 138
Rs. 150
Rs. 160

Discuss Question

Answer: Option D. -> Rs. 160
$$\eqalign{
& \text{Median} \cr
& = \frac{\text{L.V + H.V}}{2} \cr
& = \frac{120 + 200}{2} \cr
& = \text{Rs. }160 \cr}$$

Question 124. Directions (1 - 2): The graph given below shows the daily income of 50 workers in a factory. Study the graph and answer the questions.

What percentage of the factory workers earn between Rs. 150 and Rs. 180?

Discuss Question

Answer: Option B. -> 16%
Wages numbers of workers
120 12
140 26 - 12 = 14
160 34 - 26 = 8
180 40 - 34 = 6
200 50 - 40 = 10
∴Required percentage
= $$\frac{8}{50}$$ × 100 = 16%

Question 125. Directions (1 - 3): Answer the questions on the basis of following Line graph.
The change in Workforce and Productivity of Bajaj Auto For the Period 2000-2003

By how much percentage has production changed in 2003 as compared to its value for 2000?

Discuss Question

Answer: Option A. -> -3%
Change in production
= 12338 - 17213
= - 4875
% change
= $$\frac{\text{-}4875}{17213}\times100$$
= -2.9%
≈ -3%

Question 128. Directions (1 - 3): The following sketch shows the pipeline carrying material from one location to another. Each location has a demand for material. The demand Vaishali is 400, at Jyotishmati is 400, at Panchal is 700 and Vidisha is 200. Each arrow indicates the direction of material flow through the pipeline. The flow from Vaishali to Jyotishmati is 300. The quantity of material flow is such that the demands at all these locations are exactly met. The capacity of each pipeline is 1.

What is free capacity available in Avanti-Vidisha pipeline ?

Discuss Question

Answer: Option D. -> 0
Quantity moved from Avanti to Vidisha pipeline is 100 and capacity is 1000. Hence, no free capacity is available.
