How many colleges receive the accreditation of AAA?
Explanation:
The weight assigned to parameter R is highest and is at 0.4.
A college that receives 50 points on all the four parameters scores 50 out of 50.
A college that receives 40 on parameter R loses 4 points on R and can score maximum 46.
Further, a college that receives 30 or below on parameter R cannot score 45.
Therefore we need to consider only three colleges, namely A-one, Education Aid and Fancy.
A-one lost 10 × 0.3 = 3 points on I.
Education Aid lost 10 × 0.2 = 2points on P.
Fancy lost 10 × 0.2 + 10 × 0.3 = 5points on P and I.
Therefore, these three colleges receive the accreditation AAA.
