Management Aptitude Test 2014 Paper

(a) Number of students qualified gate in 2011
= 50% of 25 + 30% of 60 + 5% of 35
= $\frac{50\times 25}{100}+\frac{30\times 60}{100}+\frac{5\times 35}{100}$
= 12.5 + 18 + 1.75 = 32.25
Only 4 student gets admission, so students who do not get admission = 32.25 - 4 = 28.25
Percentage of students who do not get admission
= $\frac{28.25}{32.25}$ × 100
= 87.59688 %
Similarly, number of students qualified gate in 2012
= 50% of 30 + 30% of 60 + 5% of 40
= 15 + 18 + 2 = 35
Students who do not get admission = 35-4 = 31
∴ Percentage of students who d o not get admission
= $\frac{31}{35}$ x 100 = 88.5714%
Number of students qualified gate in 2013
= 50% of 40 + 30% of 70 + 5% of 50
= 20 + 21 + 2.5 = 43.5
Students who do not get admission
= 43.5 - 4 = 39.5
Percentage of students who do not get admission
= $\frac{39.5}{43.5}$ x 100 = 90.8045%
∴ Required aggregate percentage
= $\frac{87.5968+88.5714+90.8045}{3}$
= 89.2 %
