Answer 1

The correct option is E 147

Total number of students who qualified from school P all over the years
= 8500 + 8000 + 9500 + 6500 + 4000 + 9000
= 45500
Number of students who qualified from school together in year 2006 and 2007
= 8000 + 5500 + 9500 + 8000 = 31000
$\therefore$ Required percentage $=\frac{45500}{31000}\times 100\approx 147\%$
