Study the following table and answer the question:

Number of students enrolled for Vocational Courses (VC) in institutes A, B, C, D, E & F.

The difference between the average number of students enrolled for VC in institute F in 2015, 2017 and 2018 and the average number of students enrolled in all the six institutes in 2014, is:

85

Total number of Students enrolled in VC in F in 2015 , 2017 & 2018 = 230 + 220 + 210 = 660

Average Students enrolled in VC in F in 2015 , 2017 & 2018=(\frac{660}{3}\) = 220

Total number of Students enrolled in 2014 = 110 + 120 + 140 + 125 + 150 + 165 = 810

Average = (\frac{810}{6}\) = 135

Required difference = 220 - 135 = 85
