Radha-Govind B School has 5 branches, Ashoknagar (A), Belapur (B), Chhattisgarh (C), Laxminagar (L) & Indra Puri (I). In all these campuses, the B School take students through RAT, Radha-Govind Ability Test. Following table provides partial information on the percentage weight ages assigned to each of the parameter that they consider for their final selection (along with the score a candidate may get for each of the parameter):

Q_28-to-30_Table of the Score a Candidate may get for Each of the Parameter
	A	B	C	L	I
ACADEMIC RECORD	20	25	10	15	25
Work Experience	10	?	20	10	10
Extra-Curricular Activities [Individual: 1, Team Activity: 2]	5	0	?	5	5
Rat Result	40	30	40	?	?
Group Discussion [Scale 1-5]	15	15	20	?	15
Personal Interview [Scale 1-5]	?	15	10	15	10

For final selection, candidates are ranked based on the overall weighted score, which is the weighted average of the scores obtained in different parameters. Percentile of a person is defined by expressing the number of candidates behind that person as a percentage of the total number of candidates While collating the result, the B school observed something strange. In each campus, same set of candidates got the top 10 rank. The following table describes profiles of those10 candidates:

Q_28-to-30_1_Table of the Describes Profiles of those 10 Candidates
	Academic Record	Work Exp	Extra-Curricular	Rat	GD	PI
Ravi	65%	0.5	Basket ball	91	3	4
Kiran	78%	4.2	Hockey	82	4	5
Pragya	69%	6.3	Cricket	79	3	2
Varun	56%	2.9	Football	86	3	5
Naushad	84%	3.6	Cricket	89	5	4
Alia	81%	4.6	Book Reading	97	2	3
Thomas	59%	5.2	Cricket	83	5	3
Bharti	92%	1.6	Gardening	82	3	5
Peter	80%	2.8	Poetry	92	4	3
Nusrat	76%	3.5	Coin Collection	84	5	5

Q: 28. What is the difference between the weighted score of Ravi and Nusrat for the Ashoknagar campus?

(A) 25

(B) 3.75

(C)

(D) None of these

Ans: C

Solution:

Let’s consider the following table:

Q_28_Table of Find the Weighted Score
Parameters	Ravi’s score	Nusrat’s score	Ravi’s weighted score	Nusrat’s Weighted
A(20)	2	3	40	60
W(10)	1	2	10	20
E(5)	2	1	10	5
C(40)	3	2	120	80
G(15)	3	5	45	75
P(10)	4	5	40	50
	Overall weighted score		2.65	2.9

Q: 29. For Laxminagar campus, if extra-curricular activities carry the least weightage, then what is the range of the weighted score of Alia and Peter?

(A) Alia

(B)

(D) None of these

Ans: B

Solution:

The parameter-wise score of ALIA and PETER looks as follows:

Q_29_Table of Parameter-Wise Score
	Academic Record	Work Exp	Extra- Curricular	CAT	GD	PI
Alia	3	3	1	4	2	3
Peter	3	2	1	3	4	3

Now, since Alia’s RAT score is more than her GD score & for Peter, it’s just the reverse, hence, for Alia’s minimum weighted score, RAT result & GD should carry weightage of respectively, which would also give Peter’s maximum score. For getting Alia’s maximum & Peter’s minimum score, the weightages have to be reversed.

Alia’s maximum score of

Alia’s minimum score

Peter’s maximum score

Peter’s minimum score

Q: 30. Assuming, a total of 1000 students appear in Belapur campus, what is Bharti’s percentile in that campus?

(A)

(B)

(C)

(D)

Ans: D

Solution:

Based on the data, the following table gives the weighted score of each candidate for Belapur campus:

Q_30_Table of Weighted Score
	Academic Record	Work Exp (15)	Extra- Curricular (0)	Rat (30)	GD (15)	PI (15)	Total weighted score
Ravi	50	15	0	90	45	60	2.6
Kiran	75	45	0	60	60	75	3.15
Pragya	50	30	0	30	45	30	1.85
Varun	25	30	0	60	45	75	2.35
Naushad	75	30	0	60	75	60	3
Alia	75	45	0	120	30	45	3.15
Thomas	25	30	0	60	75	45	2.35
Bharti	100	15	0	60	45	75	2.95
Peter	75	30	0	90	60	45	3
Nusrat	75	30	0	60	75	75	3.15

Hence, 5 persons are above Bharti. Thus, Bharti’s percentile percentile.
