Study the following Table carefully and answer the questions that follow.
Note: Teacher Pupil Ratio = ‘n’ implies that there is 1 teacher for every ‘n’ students on an average;
Q15 If the total number of teachers in 2009-10 in Primary schools is 900, in Upper Primary Schools is 500 and those in High School is 350, the percentage(approximately) of the number of students in Primary School out of the total students in all schools in 2009-10 is?
(b) 56
Total Students = (900*30) + (23*500) + (27*350) = 47950 = 48000
% of Primary School students = (27000/48000)*100 ≈ 56%
