Data Interpretation – Set – An agency entrusted to accredit colleges

The following set contains four questions related to Data Interpretation. Choose the best answer to each question.

An agency entrusted to accredit colleges looks at four parameters: faculty quality (F), reputation (R), placement quality (P), and infrastructure (I). The four parameters are used to arrive at an overall score, which the agency uses to give an accreditation to the colleges. In each parameter, there are five possible letter grades given, each carrying certain points: A (50 points), B (40 points), C (30 points), D (20 points), and F (0 points). The overall score for a college is the weighted sum of the points scored in the four parameters. The weights of the parameters are 0.1, 0.2, 0.3 and 0.4 in some order, but the order is not disclosed. Accreditation is awarded based on the following scheme:

Eight colleges apply for accreditation, and receive the following grades in the four parameters (F, R, P, and I):

It is further known that in terms of overall scores:

1. High Q is better than Best Ed;
2. Best Ed is better than Cosmopolitan; and
3. Education Aid is better than A-one.

Q 1. What is the weight of the faculty quality parameter?
a) 3
b) 2
c) 4
d) 1

Q 2. How many colleges receive the accreditation of AAA?
Answer: 3

Q 3. What is the highest overall score among the eight colleges?
Answer: 48

Q 4. How many colleges have overall scores between 31 and 40, both inclusive?
a) 1
b) 0
c) 3
d) 2
Solution:
Let f, r, p and i be the weights of parameters F, R, P and I respectively.
From point I), 30f + 20r + 20p + 40i > 40f + 30r + 20p + 20i
Or 2i > f + r ————-1)
From point II), 40f + 30r + 20p + 20i > 40f + 20r + 20p + 30i
OR  r > i ———————-2)
From point III), 50f + 50r + 40p + 50i > 50f + 50r + 50p + 40i
OR i  > p ————–3)
So from eq 1) , 2) and eq 3)
r > i > p and 2i > f+r so i > f
Thus r = 0.4 , i = 0.3 , p = 0.2 and f = 0.1
Now following table can be made :

	F(0.1)	R(0.4)	P(0.2)	I (0.3)	Total
A-one	5	20	10	12	47
Best Ed	4	12	4	6	26
Cosmopolitan	4	8	4	9	25
Dominance	2	8	8	9	27
Education Aid	5	20	8	15	48
Fancy	5	20	8	12	45
Global	3	0	4	6	13
High Q	3	8	4	12	27

Now all questions can be answered.
1. d) 0.1
2. 3
3. 48
4. b) 0
