Question 62. What is the approximate percentage growth of coal production in China between the period 1981-2010?
  1.    100%
  2.    250%
  3.    450%
  4.    600%

Answer: Option C. -> 450%
:
C
Production in 1981= 0.6 bn tones
Production in 2010= 3.24 bn tones
Factor of Multiplication = 3.250.6 5.5
Hence, percentage increase= (FOM-1)×100450%
Question 63. For which of the given years is the growth in export over the previous year for tea almost equal to that of coffee?

D
On observing the graph closely, the question is about the parallelism of the two curves. We are being asked about the period in which the line graph for tea and coffee is most parallel. This happens for the year 1992.

 Discuss Question
Answer: Option D. -> 1995 and 1996
:
D
Total exports of the three Companies X, Y and Z together, during various years are:
In 1993 = Rs. (30 + 80 + 60) crores = Rs. 170 crores.
In 1994 = Rs. (60 + 40 + 90) crores = Rs. 190 crores.
In 1995 = Rs. (40 + 60 + 120) crores = Rs. 220 crores.
In 1996 = Rs. (70 + 60 + 90) crores = Rs. 220 crores.
In 1997 = Rs. (100 + 80 + 60) crores = Rs. 240 crores.
In 1998 = Rs. (50 + 100 + 80) crores = Rs. 230 crores.
In 1999 = Rs. (120 + 140 + 100) crores = Rs. 360 crores.
Clearly, the total exports of the three Companies X, Y and Z together are same during the years 1995 and 1996.
Question 65. For how many of the given regions, the ES can be said to be SO?
  1.    2
  2.    1
  3.    5
  4.    6
 Discuss Question
Answer: Option C. -> 5
:
C
Except for Middle East & Africa, all regions witness “SO” Economic Sentiment. One possible mistake that you can make here is, you might include “overall” region in your answer. That has to be avoided.
Question 66. If Dell’s revenue in 2008 was 100 million rupees and HP’s and DELL’s revenues grew at the same rate from 2009 to 2011, find the revenue of HP in 2009?

  2.    270mn
  3.    288mn
  4.    None of these
 Discuss Question

:
A
Dell’s revenue in 2011 was 180mn. Then HP’s revenue in 2011 was 360mn and HP’s revenue grew at 50% from 2009 to 2011. So, HP’s revenue in 2009 = 240mn

Question 68. In the figure shown here, there are 5 different shapes (A to E). Each shape represents the population of a village and the population is directly proportional to the area of that shape. (for eg, the population of village A is proportional to the area of shape A)
In The Figure Shown Here, There Are 5 Different Shapes (A To...
Now, assume that we want to draw a line graph to depict the population variation between the given villages. We have shown the line graph here in two of the possible ways (I and II). Which of these depicts the variation more accurately?
In The Figure Shown Here, There Are 5 Different Shapes (A To...
  1.    I only
  2.    II only
  3.    III only
  4.    None of these
 Discuss Question
Answer: Option A. -> I only
:
A
Here the approach should be to eliminate the wrong answers. This way we will be able tom save time.
Let’s analyze curve II:
This shows min population for Village C, whereas the minimum is for E. Thus not possible.
Curve III:
In reality Village C has higher population than Village B. But this curve shows the reverse. Thus not possible.
Curve I:
It shows no deviation from the expected. Thus the answer.
Question 69. For which region, the ES can be said to be VO?

B
For Middle east & Africa, there is a continuous increase. Therefore, it satisfies the criteria for VO.
