Question

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?

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;

• A. 50
• B. 56
• C. 60
• D. None of the above

Answer 1

The correct option is B 56

Total Students = $(900\times 30)+(23\times 500)+(27\times 350)=47950\approx 48000;$
$\%$ of Primary School Students = $\left(\frac{27000}{48000}\right)\times 100\approx 56\%$
