6. In which institution the percentage of the number of the students is highest as compared
to the total number of the students in all the institutions taken together in the year 2015.
Need not to calculate the percentage value in each case; as in each case the comparison is
made with “the total number of the students in all the institutions”. Hence the institution
would be with the highest number of students; therefore institution WER.
7. If the given column graph is converted to the pie chart; then find the central angle
corresponding (approximately) to the number of the students in the HIT institution in the
years 2015.
× ≅
8. If the given column graph is converted to the pie chart; then find the difference of the
central angle corresponding (approximately) to the number of the students in the ZMR
and THE institution in the years 2015.
× (~) ≅
9. If 15000 students of the institution WER are transferred to ABC institution; find the
percentage decrease in the number of the students in WER institution in the years 2015.
× ≅ %
10. If 15000 students of the institution WER are transferred to ABC institution; find the
percentage increase in the number of the students in ABC institution in the year 2015.
