Question 53. If the consumption of each petroleum product in 2011 is higher than that in 2010 then the minimum growth in total consumption in 2011 is more than:

20%
14.28%
16.66%
Cannot be determined

Discuss Question

Answer: Option A. -> 20%
:
A
Here, Let total consumption of petroleum products in 2010 is x and in 2011 is y.
Now consider the component where the percentage change between the two years is maximum (this is Kerosene)
To compute minimum growth, 12x = 10y, so x = 10 and y = 12,
Growth =

\frac{y - x}{x}

= 20%.

Question 54. Which of the following statements is necessarily true?

Total population of South Indians in the four cities together is less than 4, 60,001.

Statement 1: - The total number of people in Bangalore is less than that in Mumbai
Statement 2: - The total number of people from north India in Bangalore is more than the number of people from north India in Mumbai.

Both statements are true.
Both statements are false.
If statement 1 is true, then statement 2 is false.
If statement 1 is true, only then, statement 2 is true

Discuss Question

Answer: Option C. -> If statement 1 is true, then statement 2 is false.
:
C
Statement 1- B<M
Statement 2-

N_{B} > N_{M}

=>13% of B> 15% of M (This is possible only if B>M)
Thus, if statement 1 is true, statement 2 is definitely false.

Question 56. How much did Amar score in the QA section?
___

Discuss Question

:
Based on the answer to the previous question, the maximum score in the written test is 300, and so the maximum score in each section is 75, while the maximum score in the GD and PI is 100 each.
Thus, we can now calculate the missing percentage scores in the given table.
Amar's total percentage is 66.3, so his total score is 331.5 out of 500.
Out of this, 75 + 81 = 156 out of 200 was scored in the GD and PI
∴ He scored 175.5 out of 300 in the written test.
So, if Amar scoredxout of 75 in QA, then we have,
x +

[(50 + 68 + 72) \times \frac{75}{100}]

= 175.5

∴

175.5 - 142.5 = 33

Question 57. What is the least cost of sending petrol from refinery BB to district AAA?
