Additional directions for the last two questions of this set: If the same data as the above were used, with the additional information that the numbers of households in each category were equally distributed in all the regions then
Q. The ratio of total income for the high income category to the upper middle class increased by how much percent in the given period?
In 198788:
The total income for the high income category households = 5000 x 75000 = Rs. 37,50,00,000 The total income for the upper middle class households = 10000 x 50000 = Rs. 50,00,00,000 Thus, the required ratio for 198788 = 375000000/500000000 = 3 : 4 = 0.75 It is given that the number of households in each category is equally distributed in all the regions.
Thus, there were 5000/4 = 1250 high income household in each region in 198788.
Similarly, there were 10000/4 = 2500 upper middle class households in each region in 198788.
In the year 199495:
The percentage growth in high income households in the four regions is 245%, 425%, 175% and 150% Thus, the number of high income households throughout the country in 199495 is: 1250 x (3.45 + 5.25 + 2.75 + 2.5) i.e. 1250 x 13.95 i.e 17438 households (approx) The percentage growth in upper middle class households in the four regions is 200%, 340%, 120% and 140%
Thus, the number of upper middle class households throughout the country in 199495 is: 2500 x (3 + 4.4 + 2.2 + 2.4) i.e. 2500 x 12 i.e 30000 households (approx). Therefore Total income for the highincome households = 17438 x 1.90 x 75000 = Rs. 2,48,49,15,000. Total income for upper middle class = 30000 x 1.6 x 50000 = Rs. 2,40,00,00,000 Thus, the required ratio for 199495 = 2484915000/2400000000 = 1.035 Thus, the ratio has increased in absolute terms by 1.035  0.75 = 0.285 Hence, the required percentage increase = (0.285/0.75) x 100
= 38%
The closest option is 36%.
Hence, option 2.

Q. The average income for the Northern region in 198788, was _____.
The total income for the Northern region in 198788 = [(40000 x 30000) + (10000 x 50000) + (5000 x 75000)]/4 = (1200000000 + 500000000 + 375000000)/4
= 2075000000/4
= Rs. 51,87,50,000 The total number of household in the Norther region in 198788 = (40000 + 10000 + 5000)/4.
= 55000/4
=13750
Thus, the average income for the Northern region in 198788 = 518750000/13750
= Rs. 37,727 (approx) Hence, option 1.

Answer the following question based on the information given below.
Owing to a global economic slowdown the company Testa Ltd. has decided to review its employee compensation structure in order to cut costs. In the existing structure all 100 employees are paid a Fixed Salary (FS) equal to 10000 and a Variable Salary (VS), where the Variable Salary depends upon the performance of the company and is decided as a percentage of the Fixed Salary.
Employee salary = FS + VS The company is thinking of changing it into a variable pay structure where different groups of employees are paid as shown in the table below.
Where the Variable Salary depends on the company performance and is calculated as a percentage of Fixed salary.
Q. The company does not perform satisfactorily and decides on a variable salary = 10% of fixed salary. What is the percentage gain/loss of the company if it uses the new structure with respect to the existing compensation structure?
As there are 100 employees and VS = 10% of FS In the existing structure, the total salary would be = 100 x (10000 + 10% of 10000) = Rs. 1100000
In the proposed new structure, total salary = 60 x (8000 + 10% of 8000) + 30 x (10000 + 10% of 10000) + 10 x (12000 + 10% of 12000)
= Rs. 990000 Difference in total salary = 1100000  990000 = Rs. 110000. The company saves Rs. 110000 if it uses the new compensation structure. Percentage gain = (110000/1100000) x 100 = 10%
Hence, option 3.

Employee salary = FS + VS The company is thinking of changing it into a variable pay structure where different groups of employees are paid as shown in the table below.
Where the Variable Salary depends on the company performance and is calculated as a percentage of Fixed salary.
Q. If the variable salary is decided as 15% of the fixed salary in the existing compensation structure, what should be the percentage variable pay in the new compensation structure such that there is no difference in total employee compensation between both the structures?
YS = 15% of FS Total employee salary in the existing compensation structure = 100 x (10000 + 15% of 10000) = Rs. 1150000
Let the variable salary be x% of the fixed salary in the new compensation structure. Total salary in the new compensation structure = 60 x (8000 + x% of 8000) + 30 x (10000 + x% of 10000) + 10 x (12000 + x% of 12000)
= Rs. (900000 + 9000x)
For there to be no difference between the two compensation structures, 1150000 = 900000 + 9000x.
x = (250/9) % = 27.78% Hence, option 4.

Where the Variable Salary depends on the company performance and is calculated as a percentage of Fixed salary.
Q. The company is not satisfied with the cost savings from the new compensation structure and decides to retrench 9 employees from employee categories of A and B such that employees retrenched from category A is twice those retrenched from category B. The variable pay for the new compensation is declared to be 10%. What should be the percentage variable pay in the old compensation structure such that there is no difference between the two?
As the company retrenches 9 employees the total employees now left are 91.
Let the employees retrenched from category B be y.
Employees retrenched from category A = 2y
y + 2y = 9.
y = 3. The employees in category A, B and C are 54, 27 and 10 respectively.
Total employee compensation in the new structure = 54 x (8000 + 10% of 8000) + 27 x (10000 + 10% of 10000) + 10 x (12000 + 10% of 12000).
Let the variable salary in the old compensation structure be z% of the fixed salary Total employee compensation in the old structure = 91 x (10000 + z% of 10000) = Rs. (910000 + 9100z) For there to be no difference in the two compensation structures, 904200 = 910000 + 9100z, which is not possible So, the total compensation of both the structures can never be same.
Hence, option 4.

Where the Variable Salary depends on the company performance and is calculated as a percentage of Fixed salary.
Q. If the total variable salary component of category A employees is equal to the total salary of category C employees, in the new system, then what percentage of the fixed salary is the variable salary?
Let the variable salary be x% of the fixed salary. Then, 60 * x% of 8000 = 10 *(12000 + x% of 12000). Therefore 4800x= 12000 + 1200x.
x= 33.33%
Hence, option 1

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 c rude _{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. Hence, option 4.

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.
