Answer the following question based on the information given below.
Analyze the charts given below that show the energy consumption and energy production of XYZ country from various sources. The difference in production and consumption of energy from any source is bridged through external trade (i.e. export or import) of energy from the same source. All the values are given in Terawatthours (Twh).
Q. Which year registered the highest external trade in the energy sector?
External trade =  Imports _{coal}  +  Imports _{crude oil} I + I Imports _{Natural gas} I + I Imports _{Nuclear} I + I Imports _{others} I
Imports = Consumption  Production
In the equation above, exports have also been considered as imports i.e. a negative value of imports would actually mean an export.
From the table, the external trade is highest in the year 2013.
Analyze the charts given below that show the energy consumption and energy production of XYZ country from various sources. The difference in production and consumption of energy from any source is bridged through external trade (i.e. export or import) of energy from the same source. All the values are given in Terawatthours (Twh).
Q. In which year are the net imports of all the categories taken together the lowest?
Consider the solution to the first question.
Among the given options, net imports are lowest in 2009.
Hence, option 1.
Analyze the charts given below that show the energy consumption and energy production of XYZ country from various sources. The difference in production and consumption of energy from any source is bridged through external trade (i.e. export or import) of energy from the same source. All the values are given in Terawatthours (Twh).
Q. Which of the following statement(s) is/are true?
I. In each year, net exports are always less than the external trade.
II. Coal is always exported.
III. Net import of energy from at least one source is nil from 20092014.
Net exports =  net imports
From the table, it is always less than the external trade.
Thus, statement I is true.
Import of coal in 2014 is 150TWh.
Thus, statement II is false.
Net import of nuclear energy = 300 + 0 + 200 + 100 150 + 150 = 0
Thus, statement III is true.

Answer the following question based on the information given below.
Eight friends Raju, Ravi, Ramesh, Rahul, Arjun, Arvind, Anish and Atul are skilled at making Handicraft items. In order to make money using their skills, they decide to make a certain number of handicraft items and sell them at a Handicraft Expo. They decided to minimize time and maximize their productivity by forming two groups. The people whose names start with the letter ‘R’ form Group 1 and the people whose names start with the letter ‘A’ form Group 2. Each person from Group 1 forms a team each person from Group 2 to produce a certain number of handicraft items of a particular type, the details of which are given in the tables below.
Table 1 gives details of the type of handicraft item produced by each team.
Table 2 gives details of the number of handicraft items produced by each team.
Table 3 gives the cost price and selling price of one item of each type
The money (Cost Price and Profit) is shared according to the number of items each one has worked on. For example, if Rahul and Arvind made 175 pots, the total cost price and the profit made by selling those pots would be shared equally.
Q. Who has worked on the maximum number of handicraft items?
The number of handicraft items worked on by any person is directly given in table 2.
Raju, Rahul, Arvind and Anish have worked on 525, 500, 550 and 5
450 items respectively.
Thus, among these four people, Arvind has worked on the maximum number of handicraft items.
Hence, option 3.

Q. For how many teams was the ratio of the total cost price to the total selling price less than 0.5?
The ratio of cost price to selling price is less than 0.5 for only baskets and plates.
Hence, any team that has made baskets or plates satisfies the given conditions. 4 teams have made baskets and 1 team has made plates i.e. 5 teams satisfy the condition.
Hence, option 3.

Table 3 gives the cost price and selling price of one item of each type
The money (Cost Price and Profit) is shared according to the number of items each one has worked on. For example, if Rahul and Arvind made 175 pots, the total cost price and the profit made by selling those pots would be shared equally.
Q. Which of the following statement(s) is/are true?
I. The total profit earned by Atul is Rs. 6,000
II. The total selling price of all the items that Ramesh has worked on is Rs. 32,125
III. The team of Raju and Arjun had the lowest total selling price of the items they had produced.
Statement III can be directly verified from the solutions to one of the earlier questions.
The team of RameshAtul has the lowest selling price.
Hence, statement III is false.
Hence, options 2 and 4 can be eliminated.
Since II is present in both the remaining options, you can directly assume it to be true.
Hence, just verify I.
The total profit earned by Atul = (50/2) * 30 + (100/2) x 30 + (25/2 x 20) + (175/2 x 40) = Rs. 6,000
Thus, statement I is true.
Hence, option 1.

Q. For which type of handicraft was the total number of items 1Marks produced the highest?
The total number of items for each type of handicraft is:
Baskets = 125 + 200 + 50 + 50 = 425
Shoes = 75 + 100 + 75 + 100 + 250 = 600
Pots = 25 + 175 + 50 + 100 = 350
Lanterns = 100 + 175 = 275
Hence, option 2.

Option (1):
Percentage share of Upper primary institutions in 1999  00
Percentage share of Upper primary institutions in 2000  01 =
Increase = 21.24  20.70 = 0.54%
Percentage share of Prim ary institutions in 1999  00 =
Percentage share of Prim ary institutions in 2000  01 =
Decrease = 67.09  65.78 = 1.31%
Since the increase in percentage share of Upper primary institutions in 200001 is less than the decrease in percentage share of Primary institutions in the same period, the statement is false.
Option (2):
Percentage share o f Upper prim ary institutions in 2003  04 =
Percentage share o f Upper prim ary institutions in 2004  05 =
Decrease = 23.41  22.93 = 0.48%

Percentage share o f Prim ary institutions in 2004  05 =
Increase = 63.89  63.57 = 0.32%
Since the decrease in percentage share of Upper primary institutions in 200405 is more than the increase in percentage share of Primary institutions in the same period, the statement is false.
Option (3):
From option (1), we have already seen that the year 200001 has also seen a decline in the percentage share of primary institutions, so the statement is false.
Option (4):
Percentage sh are o f Junior colleges in 2002 03 =
Percentage share of Junior colleges in 2003  04 =
Decrease = 13.27  13.03 = 0.24%
Percentage share of Primary institutions in 2002  03 =
Percentage share of Primary institutions in 2003  04 =
Increase = 63.57  63.00 = 0.57%
Since the decrease in percentage share of Junior colleges in total in the year 200304 over the previous years is less than the increase in percentage share of primary institutions in the same period, the statement is true.
Hence, option 4.
Yearwise breakup of number of educational institutions in India:
Q. Which of the following statement(s) is/are definitely true?
Option (1):
The statement is false as the number of Primary institutions first
decreased in 200001, then increased in 200102 and again decreased in 200203.
Options (2) and (3) are true.
Hence, option 4.
Yearwise breakup of number of educational institutions in India:
Q. What is the number of years in which the total number of Upper primary schools and Junior colleges is less than half of the number of Primary schools?
The total number of Upper primary schools and Junior colleges is less than half the number of Primary schools only in the year 1999 00.
Hence, option 1.
Yearwise breakup of number of educational institutions in India:
Q. If in the year 200506, the number of Upper primary schools grows by the highest percentage growth recorded in the last 6 years (for Upper primary schools), then what is the expected number of Upper primary schools in 200506?
In the solution to the 1^{st} problem of this set, it is has been found that the highest percentage growth for Upper primary schools was 11.68% in 200203.
