However, if a candidate fulfills all the criteria except - a). at (i) above has obtained 50% marks at degree and 70%at higher secondary respectively and has at least three years experience of working, the case may be referred to the director of the firm. b). at (iii) above, but is willing to pay an amount of 1 lakh if required to leave, the case may be referred to the president of the firm c. at (ii) above but is a computer engineer, the case may be referred of DGM. Based on the above criteria and the information given in each of the following cases, you have to take the decision on employing a candidate. You are not to assume anything and in the absence of adequate information, your answer will be not to be selected. The case is given to you as on 1.2.2007.
Q. No. 1:
Amar is a mechanical engineer with 65% marks at degree and 88% marks at HSC. He completed his engineering degree in 2003 at the age of 22 years and immediately started working in an engineering firm. He id keenly interested in going to USA and is not ready to sign a bond. However, he has not mind paying an amount of Rs. 1 lakh
Answer: B Amar satisfies the conditions in (i) and (iv). He does not meet the condition in (iii) but as he is willing to pay an amount of Rs.1 lakh, if required to leave the software firm, his case could have been referred to the “President” of the firm. We are given that in 2003, he had started working for an engineering firm but we have no information on the duration of his employment in that firm, hence we cannot conclude that he satisfies the condition of having at least one year’s experience which is required as per condition (ii). Due to lack of this information, he should not be selected. Hence (B) is the correct answer.
Q. No. 2:
Raj kishore, a computer engineer, has just completed graduation in July 2006, at the age of 23 years obtaining 72% marks. He had obtained 92% marks in HSC. He is willing to sign a bond with the company. He was joined a software company as trainee in August 2006 and working there till date

Further, there is no information on either her acceptance or her nonacceptance of the condition of bond in (iii). Hence, due to lack of information, she should not be selected and (B) is the correct answer.
Q. No. 4:

Except for one person who was 22 years old and one person who was 28 years old all other four persons were 25 years. Each of the six persons have a different weight and their weights (in kgs) were 56 , 48 , 62 , 67, 72 and 75. The person who bought ‘Spark’ was of the same age as Preeti.

The youngest person weighed more than Shweta but less than exactly two males. Raju weighed more than Ryan.
Answer: D Given that except for one person who was 22 years old, all other persons
were either 25 years or 28 years old and there is only one person who
is 28 years old, therefore there are four persons who are 25 years
old. Also, the person who was 28 years old weighs 72
kgs. The person who bought ‘Fabia’ is 22 years old as he/she is
three years younger to the person who weighs 75
kgs. Therefore, the age of the person who weighs 75 kgs is
25. Since, the person who bought ‘Fabia’ is 22 years old,
therefore the person who bought ‘A – star’ is 28 years
old. Since, the two females have bought ‘i10’ and ‘Swift’,
therefore a male has bought ‘Fabia. Now, we know that a male
has bought ‘A – star’, is 28 years old and weighs 72
kgs. Since, it is given that a female who bought ‘i10’ weighs
more than 67 kgs, therefore the female who bought ‘i10’ weighs 75
kgs. Since, Samar weighs less than Rohan, therefore Rohan
bought ‘A – star’ and Samar bought ‘Fabia’. Since, the youngest
person weighs more than Shweta, therefore Preeti weighs 75
kgs. If we collect the whole information we can conclude the

kgs. The person who bought ‘Fabia’ is 22 years old as he/she is
three years younger to the person who weighs 75
kgs. Therefore, the age of the person who weighs 75 kgs is
25. Since, the person who bought ‘Fabia’ is 22 years old,
therefore the person who bought ‘A – star’ is 28 years
old. Since, the two females have bought ‘i10’ and ‘Swift’,
therefore a male has bought ‘Fabia. Now, we know that a male
has bought ‘A – star’, is 28 years old and weighs 72
kgs. Since, it is given that a female who bought ‘i10’ weighs
more than 67 kgs, therefore the female who bought ‘i10’ weighs 75

Each of the given families have exactly two children. Two out of the four families have a boy and a girl each, one family has two girls and the Ahuja’s have two boys. Jatin (boy) belongs to family A. Family B and the Sharma’s have at least one girl. Kamini (girl) does not belong to the Khanna’s. Rahul (boy) belongs to family C. Preeti (girl) and Akash (boy) do not belong to the same family. Amit (boy) does not have a sister. Jyoti(girl) belongs to one of the given families. Sarika (girl) does not belong to the Sinha’s and belongs to the same family as Kamini. The Sinha’s are not disguised as B. Rahul does not belong to the Ahuja’s.
Q. No. 1:
To which of the following families does Preeti belong?
Answer: D Given that the Ahuja’s have two boys and Amit does not have a sister,
which means that Amit belongs to the Ahuja’s. Given that the
family B and the Sharma’s have at least one girl and the Sinha’s are not
disguised as B, therefore the Khanna’s are disguised as
B. Also, Kamini belongs to either the Sinha’s or the Sharma’s.
Given that Sarika does not belong to the Sinha’s and belongs to the same
family as Kamini. So, both Sarika and Kamini belong to the Sharma’s.
Given that Rahul belongs to family C and Jatin belongs to family A,
therefore the Sharma’s are disguised as D. Since, Preeti and
Akash do not belong to the same family, therefore Jyoti belongs to
family B. Also, Amit belongs to either family A or

The question given below are based on the following information ::
Four persons named Aditya, Ashish, Kriti and Ritika visited a luxury shopping mall in South Delhi to buy denims. The mall had several designer outlets, which were either national or international. Further, it is known that: 1. Each of these persons bought denims from 2 designer outlets, exactly one of which was national. 2. No two persons bought denims from the same designer outlet. 3. The number of denims bought by these four persons from any designer outlet were all different and prime. 4. The total number of denims bought by Ashish from a national designer outlet were less than that bought from an international designer outlet. This was true for the other three persons as well. 5. The total number of denims bought by Aditya, Ashish, Kriti and Ritika were 36, 25, 32 and 28 respectively.
Q. No. 1:
For which of the following persons, the number of denims bought from a national designer outlet by him/her can be exactly determined?
Answer: C Let us first write the numbers 36, 25, 32 and 28 as a sum of
two different prime numbers. 36 = (5 + 31) = (7 + 29) =
(13 + 23) = (17 + 19) 25 = (2 + 23) 32 = (3 + 29) =
(13 + 19) 28 = (5 + 23) = (11 + 17) Consider
information (3): We can conclude that the number of denims bought by
Ritika from the two outlets cannot be 5 and 23 as Ashish bought 2 denims
from one outlet and 23 from another. Also, the number of
denims bought by Aditya from the two outlets cannot be 13 and 23 as
Ashish bought 2 denims from one outlet and 23 from
another. Similarly, we can conclude that the number of denims
bought by Aditya from the two outlets cannot be (17 and 19) as Ritika
bought 11 denims from one outlet and 17 from
another. Therefore, the number of the denims bought by the
persons could be: Case

National designer outlet

Q. No. 2:
If the number of denims bought by Aditya from a national designer outlet were more than that bought by Kriti, then the number of denims bought by Aditya from a international designer outlet were
Answer: A Let us first write the numbers 36, 25, 32 and 28 as a sum of
two different prime numbers. 36 = (5 + 31) = (7 + 29) =
(13 + 23) = (17 + 19) 25 = (2 + 23) 32 = (3 + 29) =
(13 + 19) 28 = (5 + 23) = (11 + 17) Consider

Ritika from the two outlets cannot be 5 and 23 as Ashish bought 2 denims
from one outlet and 23 from another. Also, the number of
denims bought by Aditya from the two outlets cannot be 13 and 23 as

(13 + 23) = (17 + 19) 25 = (2 + 23) 32 = (3 + 29) =
