QUESTION: 1

The following three items are based on the graph given below which shows imports of three different types of steel over a period of six months of a year. Study the graph and answer the three items that follow.

The figures in the brackets indicate the average cost per ton over six months period.

Q. By how much (measured in thousands of tons) did the import of sheet steel exceed the import of coil steel in the first three months of the year?

[2018]

Solution:

Total import of sheet steel in first three months = 40 + 37 + 36 = 113

Total import of coil steel in first three months = 30 + 31 + 33 = 94

Required value = 113 – 94 = 19.

QUESTION: 2

The following three items are based on the graph given below which shows imports of three different types of steel over a period of six months of a year. Study the graph and answer the three items that follow.

Q. What was the approximate total value (in $) of sheet steel imported over the six months period?

[2018

Solution:

Total sheet steel important over six months period = 40 + 37 + 36 + 36 + 34 + 34 = 217

Total value = 217 × 256 = 55552 = 55550

QUESTION: 3

The following three items are based on the graph given below which shows imports of three different types of steel over a period of six months of a year. Study the graph and answer the three items that follow.

The figures in the brackets indicate the average cost per ton over six months period.

Q. What was the approximate ratio of sheet steel and scrap steel imports in the first three months of the year?

[2018

Solution:

Total sheet steel imported in first three months = 40 + 37 + 36 =113

Total scrap steel imported in first three months = 32 + 34 + 32 = 98

Required ratio = 113 : 98 = 1.2:1

QUESTION: 4

With reference to the above graph, which of the following is/are the most logical and rational inference/ inferences that can be made?

1. During the given period, the revenue from Direct Taxes as percentage of gross tax revenue has increased while that of Indirect Taxes decreased.

2. The trend in the revenue from Excise Duty demonstrates that the growth of manufacturing sector has been negative during the given period.

Select the correct answer using the code given below.

Therefore, during the given period, the revenue from direct taxes as percentage of gross tax revenue has increased while that of indirect taxes decreased.

2. From the graph, it is clear that exercise duty is over all decreased tremendeusly. But after 2010, exercise duty increases slightly. This traineds of exercise duty has many reasons. One of then may be decreasing rate of exercise duty to promote manufacturing sector thats why after 2010 exercise duty increases slightly.

[2018]

Solution:

According to the table tele-density is similar to others

QUESTION: 6

Consider the following graphs. The curves in the graphs indicate different age groups in the populations of two countries A and B over a period of few decades:

With reference to the above graphs, which of the following are the most logical and rational inferences that can be made?

1. Over the last two and a half decades, the dependency ratio for country B has decreased.

2. By the end of next two and a half decades, the dependency ratio of country A will be much less than that of country B.

3. In the next two decades, the work-force relative to its total population will increase in country B compared to country A.

Select the correct answer using the code given below.

[2018]

Solution:

Dependency Ratio

1. In country B, over the last two and a half decades (2025 to 2050), the sum of the number of people aged less than 15 years and more than 64 years is slightly increased but number of people aged from 15 to 64 years increased tremendously. Therefore dependency radio of country B has decreased over the last two and half decades.

2. By the end of next two and a half decades (i.e. 2075), sum of the number of people aged less than 15 years and more than 64 years of country A is more than that of country B where as number of people of aged from 15 to 64 years of country A is less than that of country B.

Hence by the end of next two and a half decades, the dependency ratio of country A will be more than that of country B.

3. In the next two decades (i.e. 2050-2070), graph of workforce (i.e. population of aged from 15 years to 64 years) of country A is going lower and that of country B is going higher.

Therefore, in the next two decades, the work-force relative to its total population will increase in country B as compared to country A.

QUESTION: 9

Consider the following figures A and B:

The manufacturing cost and projected sales for a product are shown in the above figures A and B respectively. What is the minimum number of pieces that should be manufactured to avoid a loss?

[2018]

Solution:

Manufacturing cost of 1000 pieces = 600000

Cost of 1 piece when 1000 pieces manufactured

Selling price of 1 piece when 1000 pieces manufactured = 400

Manufacturing cost of 2000 pieces = 700000

Cost of 1 piece when 2000 pieces manufactured

Selling price of 1 piece when 2000 pieces manufactured = 350

Hence, required number of pieces = 2000

The following table shows the marks obtained by two students in different subjects :

The difference in the mean aggregate percentage marks of the students is

[2014]

Solution:

For A Agg marks = 60 + 70 + 50 + 30 = 210

Agg max marks = 100 + 100 + 100 + 50 = 350

For B:

Agg marks = 80 + 70 + 60 + 15 = 225

Agg max marks = 150 + 100 + 100 + 25 = 375

Difference in agg percentage = 0

Note: Difference in agg percentage is same as difference in mean agg percentage.

Q. What is the difference between the average profit of B and A in the year 1998?

[2014]

Solution:

From the graph, we observe that the difference between points A & B is more than half of 1000, but less than 1000.

∴ 500 < |Difference between A and B| < 1000.

From the option, + 600 satisfies this condition.
