XAT Data change over a period Questions

From the above table, it is clear that the decreasing order of gain of vote share = BCEDA

D is the correct answer.

Using the data in the table, we can calculate the number of neutral votes for each party as follows:

Party B: 108128 * (100 - 30.4 - 29.7)/100 = 43143

Party C: 96620 * (100 - 32.50 - 26.60)/100 = 39517

Party D: 41524 * (100 - 30.60 - 36.10)/100 = 13827

Party E: 32724 * (100 - 21.60 - 41) /100 = 12239

Thus, we can see that Party B has the maximum number of neutral votes.

Hence, option A is the correct answer.

The table representing the Vote share of parties in the years 2000 and 2010 is as follows.

From the table, we can see that 2 and 7.5 are possible values.

Party E’s votes in 2000 are less than 2% of the total votes as given in the question. Thus, the Gain in vote share will be between 3 and 5%.

Thus, only 2.5% is the option that is not possible.

Hence, option B is the answer.

The table representing the Vote share and Tweet share in the year 2010 is as follows:

The table shows that the maximum difference between the vote share and tweet share is for “Other” parties.

Hence, option E is the correct answer.

From the above table, it is clear that the percentage increase in the number of Indians going abroad was greater than the percentage increase in the number of domestic tourists

for the years 2005 and 2007

C is the correct answer.

from the above table, it is clear that the value of rupee wrt to the dollar is cheapest in the year 2002

Hence B is the correct answer.

If we try to plot a pie chart using the values of R for all the years, 2011 will subtend maximum value since its R value is maximum among all the years.

Angle = $$\frac{2633.39}{26415.49}\times\ 360^0$$

=35.88 = $$36^{0}$$ approximately.

C is the correct answer.

Current account balance = Current account balance percentage of GDP*GDP

Current account balance in 2010 = 3.268% of 73555.34 = 2403.7885
Current account balance in 2005 = 1.272% of 35662.2 = 453.623

Ratio = 2403.7885/453.623 = 5.3 (approximately).
Therefore, option E is the right answer. 

The table provides details only regarding the % change in the imports and exports. We do not have any detail regarding the base value. Therefore, we cannot find out the absolute values and hence, statements 1 and 2 cannot be verified. 

The percentage change of exports and imports over the given period can be found out. Among the given options, option C is the only viable option now. Since none of the above is not present among the options, option C must be the right answer. 

To actually compare the growth rate of export and import. we can multiply the rates to find the net change and then compare.

Population = GDP/GDP per capita
In 2006, GDP = Rs.41159.73 billion
GDP per capita = Rs. 36,553.93
=> Population = 41159.73*1000/36553.93
                      = 1126 million.

From the table, we can see that 8.9% of the total population was unemployed in 2006. 
=> Number of unemployed people = 0.089*1126 = 100 million (approx)
Therefore, option A is the right answer. 

Expenditure on roses in January = 1136916

Price of roses per dozen = 99

Roses sold = 1136916/99

                =11484 dozens

Expenditure on roses in July = 1188432

Price of roses per dozen = 144

Roses sold = 1188432/144

                =8253 dozens 

Sales of roses in July as compared to January = [(8253-11484)/11484]*100

                                                                    =  - 28.13%

Since Change is negative, there is a decrease of 28.13%.
Hence B is the correct answer.

Total population = 70000

Average consumer expenditure on Roses and carnations = 47.4

Total expenditure on both carnations and roses = 47.4*70000

                                                                       = 3318000

Given total expenditure on roses = 1136916

So the total expenditure on carnations = 3318000 - 1136916

                                                           = 2181084

Sales of carnations in January = 13848 dozens

Price of carnation  per dozen  in January =2181084/13848

                                                              = 157.5 

Similarly In December 

Average consumer expenditure on Roses and carnations = 56.4

Total expenditure on both carnations and roses = 56.4*70000

                                                                       = 3948000

Given total expenditure on roses = 977688

So the total expenditure on carnations = 3948000 - 977688

                                                           = 2970312

Sales of carnations  = 18859 dozens

Price of carnation  per dozen  in January =2970312/18859

                                                              = 157.5

Therefore the price did not change

Hence E is the correct answer 

Total population = 70000

Average consumer expenditure on Roses and carnations = 47.4

Total expenditure on both carnations and roses = 47.4*70000

                                                                       = 3318000

Given total expenditure on roses = 1136916

So the total expenditure on carnations = 3318000 - 1136916

                                                           = 2181084

Similarly in the month of March 

Average consumer expenditure on Roses and carnations = 49.5

Total expenditure on both carnations and roses = 49.5 *70000

                                                                       = 3465000

Given total expenditure on roses = 1137915

So the total expenditure on carnations = 3465000 - 1137915

                                                           = 2327085

Percentage increase in Expenditure  = (2327085-2181084)/2181084

=6.69%

Hence C is the correct answer

Let (Costs / Sales Revenue) * 100 = x%

(Profit / Sales Revenue) * 100 = (100-x) % 

(Profit / Sales Revenue) = (100-x) /100 % 

(Profit / Price * Sales Quantity) =(100-x) /100 % 

Profit / Sales Quantity =[(100-x) /100]* Price  

On tabulating the Profit rate of both the factories , we get 

Clearly C is the correct answer

For Jan- Mar 2009 Paharpur cement 

Sales Quantity = 543278 

Cost as percentage of revenue = 87.56 % 

Profit as a percentage of revenue = 100-87.56

                                                   = 12.44 % 

Profit = (12.44/100)* 543278 *304

         = 20545470

Profit rate = 37.82

For Jan- Mar 2009 Bahsin Cement 

Sales Quantity = 526532 

Cost as percentage of revenue = 91.34 % 

Profit as a percentage of revenue = 100-91.34 

                                                   = 8.66 % 

Profit = (8.66/100)* 526532*440

         = 20062975.3

Profit rate = 30.5

For Apr- Jun 2009 Paharpur cement 

Sales Quantity = 698236

Cost as percentage of revenue = 91.03% 

Profit as a percentage of revenue = 100-91.03

                                                   = 8.97 % 

Profit = (8.97/100)* 698236*340

         = 21294801.53

Profit rate = 30.5

For Apr- Jun 2009 Bahsin Cement 

Sales Quantity = 499874

Cost as percentage of revenue = 89.96% 

Profit as a percentage of revenue = 100-89.96 

                                                   = 10.04 % 

Profit = (10.04/100)* 499874*430

         = 21580560.33

Profit rate = 43.17

Hence E is the correct answer

Let the Sales of Paharpur Cement during Apr - Jun 2009 be x 

Therefore  profit = [(100-91.03)*340*x]/100

                          = 30.498x

the Sales of Paharpur Cement during Jul- Sept 2009 increased by 2.25%

Therefore Sales of Paharpur Cement during Jul- Sept 2009 is 31.54x 

Percentage increase in profit = (31.54x-30.498x)/30.498x

                                            = 3.42%

Hence E is the correct answer
