SRCC GBO 2022 Question Paper

Percentage changes (2017 to 2018)

Imports: From 400 to 450

Increase = 50/400 = 12.5%

Exports :From 360 to 320

Decrease = 40/360 = 11.11%

Exports in 2020

2019 value = 400

Decrease by 11.11%

400×(1−0.1111)=355.6

Imports in 2020

2019 value = 480

Increase by 12.5%

480×1.125=540

Difference = 540 - 355.6 = 184.4

The percentage by which exports were less than imports (2020)

(184.4/540)*100 = 34.2%

average exports (per year) in 2015, 2018 and 2019 : (240+320+400)/3 = 320

Imports in 2018: 450

Difference = 130

Difference percentage = (130/450)*100 = 28.9%

It is given that total expenditure in January = ₹54,000

And, the expenditure is December is 20% more than that in January = 20% of 54000 + 54000 = ₹ 64800

Expenditure on items A,B,C,D,E and F in January

A = 20% of 54000 = 10800

B = 15% of 54000 = 8100

C = 18% of 54000 = 9720

D = 25% of 54000 = 13500

E = 12% of 54000 = 6480

F = 10% of 54000 = 5400

Similarly, Expenditure on items A,B,C,D,E and F In December.

A = 18% of 64800 = 11664

B = 12% of 64800 = 7776

C = 16% of 64800 = 10368

D = 21% of 64800 = 13608

E = 20% of 64800 = 12960

F = 13% of 64800 = 8424

The question is "The expenditure on item D in December is ₹108 more than the total expenditure in January over items:"

The expenditure on item D in December is = 13608

Option A) Expenditure of item C and E in January = 9720 + 6480 > 13608

Option B) Expenditure of item B and C in January = 8100 + 9720 > 13608

Option C) Expenditure of item B and F in January = 8100 + 5400 = 13500

Thus, we can see that The expenditure on item D in December is ₹108 more than the total expenditure in January.

Hence, Option C is the correct answer.

It is given that total expenditure in January = ₹54,000

And, the expenditure is December is 20% more than that in January = 20% of 54000 + 54000 = ₹ 64800

Expenditure on items A,B,C,D,E and F in January

A = 20% of 54000 = 10800

B = 15% of 54000 = 8100

C = 18% of 54000 = 9720

D = 25% of 54000 = 13500

E = 12% of 54000 = 6480

F = 10% of 54000 = 5400

Similarly, Expenditure on items A,B,C,D,E and F In December.

A = 18% of 64800 = 11664

B = 12% of 64800 = 7776

C = 16% of 64800 = 10368

D = 21% of 64800 = 13608

E = 20% of 64800 = 12960

F = 13% of 64800 = 8424

The average expenditure on items A, C and D together in January is what per cent less than the expenditure on item E in December?

The average expenditure on items A, C and D together in January is = (10800+9720+13500)/3 = 11340

Tthe expenditure on item E in December = 12960

It is less by [(12960- 11340)/12960]*100 = 12.5%

Option D is the correct answer.

It is given that total expenditure in January = ₹54,000

And, the expenditure is December is 20% more than that in January = 20% of 54000 + 54000 = ₹ 64800

Expenditure on items A,B,C,D,E and F in January

A = 20% of 54000 = 10800

B = 15% of 54000 = 8100

C = 18% of 54000 = 9720

D = 25% of 54000 = 13500

E = 12% of 54000 = 6480

F = 10% of 54000 = 5400

Similarly, Expenditure on items A,B,C,D,E and F In December.

A = 18% of 64800 = 11664

B = 12% of 64800 = 7776

C = 16% of 64800 = 10368

D = 21% of 64800 = 13608

E = 20% of 64800 = 12960

F = 13% of 64800 = 8424

Total Expenditure for January = 54000.
December's expenditure is 20% more than January's i.e. 1.2*54000 = 64800.
Now, we calculate month wise distribution of expenditures on the given items.

The item on which there is 4% decrease in December as compared to January is B.

If 25% of the male employees in offices A are transferred to office C, then the number of male employees in Office C are 128 + 25% of 384 = 224.
And, if 35% of female employees in D are transferred to office E, then the number of female employees in E are 16 + 35% of 240 = 100.
The required percentage = $$\frac{100}{224}\times\ 100\approx\ 44.6\%$$

Male employees in Office E = $$\frac{50.4}{360}\times\ Total$$. 
This gives the total number of male employees = 1600.
Total male employees in offices C and F = $$\frac{28.8+32.4}{360}\times\ 1600\ =\ 272$$.

Total employees in Office C = $$\frac{43.2}{360}\times\ Total$$.
This gives the Total number of employees = 2400.
Total employees in Office B = $$\frac{64.8}{360}\times\ 2400\ =\ 432.$$
The required ratio = 272:432 = 17:27.

Using the table, 

the number of female employees as a percentage for male employees is: 31.25%, 80%, 125%, 50%, 7.14% and 50% for the offices A, B, C, D, E and F respectively.
The number of female employees as a percentage of male employees is second lowest in office A.

Number of male employees in E = $$\frac{50.4}{360}\times\ Total\ Male$$ i.e. 224.
This gives the number of Total male employees = 1600.
And Total employees in C = $$\frac{43.2}{360}\times\ Total$$ i.e. 288.
This gives the Total number of Employees = 2400.
Using these values, we can calculate Total number of Employees and Total number of Female employees for all the offices.

average number of male employees in offices A, D and F = 336 and the total number of female employees in offices B, E and F are 280.
The required percentage = $$\frac{336-280}{280}\times\ 100\ =\ 20\%$$.
