Question 53

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:

Solution

The average number of students enrolled for VC in institute F in 2015, 2017 and 2018 = $$\frac{230+220+210}{3}$$ = 220

The average number of students enrolled for VC in all the six institutes in 2014 = $$\frac{110+120+140+125+150+165}{6}$$ = $$\frac{810}{6}$$ = 135

Required difference = 220 - 135 = 85

Hence, the correct answer is Option D
