Solution:

2007-08

Students appearing in Class X examination = 1,05,332

Number of students passing = 88,151

Pass % for the year 2007-08 = (88,151/1,05,332) × 100

= 0.8369 × 100

= 83.69%

2008-09

Students appearing in Class X examination = 1,16,054

Number of students passing = 1,03,804

Pass % for the year 2007-08 = (1,03,804/1,16,054) × 100

= 0.8944 × 100

= 89.44%

There is an increase in the past percentage from the year 2007-08 to 2008-09 from 83.69% to 89.44% which is an increase of 5.75%
