following years the number of students selected is maximum?
(a) 2008
(b) 2009
(c) 2010
(d) 2011
(e) 2012

Selected students in 2012 = 45% of 75000
= 75000 x 45/100 = 33750
So, % Difference = 40500 – 33750/33750
x 100
= 6750 x 100/33750 = 20%
4. What is the ratio
of the number of students who are not selected in the year 2011 to the number

(a) 3 : 2
(b) 4 : 3
(c) 5 : 4
(d) 7 : 5
(e) 8 : 7

Students not selected in 2011 = 40% of 80000
= 32000
Selected students in 2008 = 40% of 70000

So, Ratio = 32000/28000 = 8/7
= 8 : 7
