Question 31. What is the percentage change in temperature gradient in stage II over that in stage III?
  1.    40
  2.    33.33
  3.    51
  4.    Cannot be determined
 Discuss Question
Answer: Option C. -> 51
:
C
Temperature gradient in stage II = (7525100) = 12deg C /min
Temperature gradient in stage III =(25(5)90) = 13deg C/min
So percentage change = (0.50.330.33) = 50%
Question 32. How many centuries did Sachin score in ODI?
  1.    51
  2.    49
  3.    50
  4.    Cannot be determined
 Discuss Question
Answer: Option B. -> 49
:
B
After concluding only test matches’ centuries, we will get the answer as shown in the table.
Question 33. The total demand for Cotton in 2005-06 in Country X is nearly balanced by the total supply of ______ in 2005-06.
  1.    Food
  2.    Food & Cotton
  3.    Oil, Food & Plastic
  4.    Oil & Silk
 Discuss Question
Answer: Option C. -> Oil, Food & Plastic
:
C
This question can be solved using the Factor of Multiplication(FOM) between both graphsFOM = 20635201023531 = 2010 2
Thus, since the cotton percentage is 32% in the Demand Graph, a similar value in the Supply Graph will be obtained by multiplying 32 with its factor of multiplication (2) = 32 × 2=64%.
Look at the answer options. Only option (c) – Oil +Food+Plastic =40+23+1= 64%. You can directly mark answer (c)
Question 34. In the health category, the number of articles published in December 2002 as compared to June 2003
  1.    was larger
  2.    was smaller
  3.    was equal
  4.    Cannot be determined
 Discuss Question
Answer: Option A. -> was larger
:
A
Let total number of articles published in December 2002 and June 2003 be ‘x’ and ‘y’ respectively
Then we know that x>y => .19x>.18y
Question 35. Which of the following can be the number of centuries scored by Sachin against Bangladesh in ODIs?
  1.    0
  2.    1
  3.    3
  4.    4
 Discuss Question
Answer: Option B. -> 1
:
B
We can have two possible scenarios.
i) Sachin scores a century against Namibia. Then he scores 6 centuries against Bangladesh. Hence centuries in ODI = 1
ii) Sachin does not score a century against Namibia. Then he scores 7 centuries against Bangladesh. Hence centuries in ODI = 2
So of the given options only option(b) is possible
Question 36. In the financial category, the number of articles published in September 2002 as compared to March 2003
  1.    was larger
  2.    was smaller
  3.    was equal
  4.    Cannot be determined
 Discuss Question
Answer: Option D. -> Cannot be determined
:
D
We know that the total number of articles published in Sept 02> Mar 03. However, we cannot compute if 25% of Sept 02> 37% of Mar 03. The exact values of total number of articles published in the two months or the ratio between the number of articles in September 02 and March 03 is required to solve the question.
Question 37. What is the ratio of temperature gradient to pressure gradient in the process?
  1.    400 : 9
  2.    40:18
  3.    18:40
  4.    80:18
 Discuss Question
Answer: Option A. -> 400 : 9
:
A
Temperature gradient =(35+5)5= 8 deg C /hr
Pressure gradient = 0.18 bar/hr
So ratio = 800 : 18 = 400 : 9
Question 38. For which sector is the number of male employees the minimum?
  1.    HR
  2.    IT
  3.    Marketing
  4.    None of these
 Discuss Question
Answer: Option D. -> None of these
:
D
The total number of employees in IT sector = 1800 × 13100= 234
Number of female employees = 1200 × 14100= 168
Number of male employees = 234 – 168 = 66.
Now total number of employees in H.R = 1800 × 12100 = 216
Number of female employees = 1200 × 14100 = 168
Number of male employees = 216 – 168 = 48.
The total number of employees in finance sector = 1800 × 20100 =360
Number of female employees = 1200 × 30100 = 360
Number of male employees = 360 – 360 =0
Question 39. If the supply is growing at an annual rate of 10%, then the supply in 2009-10 is nearest to?
  1.    1498551
  2.    1656765
  3.    1765431
  4.    1233211
 Discuss Question
Answer: Option A. -> 1498551
:
A
The answer is based on1023531 × 1.14 102 × 112 ×112 104 × 12 ×12 14_______
Since there is only one answer option starting with 14, you can mark the answer as option (a)
