Answer»

In 2016,

TOTAL no. of students appearing in 12th examination = 37023 + 1811 + 32498 + 737 = 72069

Total no. of schools = 954

Required AVERAGE for 12th examination = 72069/954 = 75.54 ≅ 76

Similarly,

Total no. of students appearing in 10th examination = 91172 + 1728 + 74885 + 806 = 168951

Total no. of schools = 2015

∴ Required average for 10th examination = 168951/2015 = 83.85 ≅ 84
