employees in an organization across five departments. The following table gives
the department-wise distribution of average age, average basic pay and
allowances. The gross pay of an employee is the sum of his/her basic pay and
allowances.
transfer/promotion across departments. Whenever a person is
transferred/promoted from a department of lower average age to a department of
higher average age, he/she will get an additional allowance of 10% of basic pay
over and above his/her current allowance. There will not be any change in pay
structure if a person is transferred/promoted from a department with higher
average age to a department with lower average age.

Answers with explanations:
1. Correct Answer: C The person who joined finance from marketing is 20 years elder to the person who joined marketing from finance. ( As the average age increased by 1 for 20 people ). Avg age of marketing department remains the same.
Marketing dept’s net loss is one person so there should be a total reduction of 35 years. 20 years Marketing department “lost” to fin. which means the guy who moved to HR is 15 years old. so HR dept’s ( now 5 + 1 ) avg age = ( 45 * 5 + 15 ) / 6 = 40 years.
2. Correct Answer: C
Explanation :
HR dept’s avg age is 45 and marketing dept’s avg age is 35. Transfer from lower avg age to higher avg age means 10% additional allowance of basic pay.
Guy from marketing has an allowance of 80% of 8000 = 6400,
new allowance = 6400 * ( 1 + 10/100) = 7040.
new gross pay of the transferred person = 8000 + 7040 = 15040.
Initial avg gross pay of HR = 5000 + 70/100 * 5000 = 8500.
New average gross pay of HR (after transfer) = ( 8500 * 5 + 15040 ) / 6 = 9590.
Hence, % change = (9590 – 8500)/8500 ~ 13.
3. Correct Answer: B
Explanation :
new avg basic pay after the transfer,
(5 * 5000 + 2 * 6000 + 8000)/8 = 5625
% change = (5625 – 5000/5000) * 100 = 12.5%
4. Correct Answer: A
Explanation :
Let the CP of the article be Rs x.
Since, he earns a profit of 20% hence S.P = 1.2x .
It is given that he incurs loss by selling 16 articles at the cost of 12 articles.
loss = (16-12)/16 = 25%
His selling price = SP * 0.75 = 1.2
Hence, SP * 0.75 = 1.2 x.
or, SP = (1.2x)/0.75 = 1.6x.
this SP is after giving a discount of 20% on MP.
Hence, MP = 1.6x/.08 = 2x.
This means that the article has been marked 100% above the cost price.
5. Correct Answer: A
Explanation :
Asha=25 Nisha =n Usha =3n
Asha=2a Nisha =a Usha =34
The difference of all ages must be same
=> 25-2a=n-a=3n-34
We will get two equation
=> 2n+a=34
=> n+a=25
From the equation we will get n=9 and a=16
The ages are Asha=2a=32 Nisha =16 and Usha =34
Sum of the ages =100
=> (32+x)+(16+x)+(34+x)=100
=> 82+3x=100
=> 3x=18
=> x=6
=> Age of Usha =34+6=40
Hence (A) is the correct answer.
6. Correct Answer: A
Explanation :
Using Formula of Compound Interest
=> CI=p(1+R/100)15 = 2p
=> = (1+R/100)^15 —>(1)
If it is 8P, n=?
P(1+R/100)n = 8P
(1+R/100)n = 8
(1+R/100)n = 23
Substitute ,
=> 2=(1+R/100)15
(1+R/100)n=((1+R/100)15)3
(1+R/100)n=(1+R/100)45
n=45
So after 45 years it will become 8 times.
(7-10): From the data that is given we can extrapolate the following data:
7. Correct Answer: D
The exports related to food in 85-86 = 0.23 x 25800 = 5934.
Therefore the exports related to food 1984-95 = (5934 – 1006) = 4928. Therefore the percentage foo d related exports in 84-85 = 4928/22400 = 22%.
8. Correct Answer: B
The Value of Manufactured articles & Raw materials exports In 84-85, = (22400 – 4928) = Rs.17472 crore. Since Export in manufactured goods is twice that of raw materials, Therefore the ratio of export o f manufactured goods and raw materials is 2:1
Therefore export of manufactured goods = Rs.11648 crore and Raw materials = Rs.5824 crore
Hence the difference between raw material and food = (5824 – 4928) = R s.896 crore
9. Correct Answer: D
The combined percentage of Manufactured articles and Raw materials in 85-86 = 77%
And therefore the ratio will be 4 : 3.
Therefore the percentage of Manufactured articles export = 44% The percentage of Raw materials export = 33%.
Therefore value of manufactured = 0.44 x 25800 = Rs.11352 crore And the value of Raw materials = Rs.8514 crore
Therefore the percentage difference between the value of Raw materials between 84-85 and 85-86 = [(8514 – 5824)/8514] × 100 = 31.6%
10. Correct Answer: A
The change in value of export s of manufactured articles from 1984 – 85 to 1985 – 86 = (11648 – 11352) = Rs.296 crore
