What is the sum of the average number of students enrolled for VC in institute B in 2014, 2015 and 2017 and the average number of students enrolled in institute E in 2013 and 2018? Correct Answer 260

Students enrolled in B 2014 = 132

Students enrolled in B 2015 = 138

Students enrolled in B 2017 = 135

Total in three years = 132 + 138 + 135 = 405

Average = 405/3 = 135

 

Students enrolled in E 2013 = 105

Students enrolled in E 2018 = 145

Total in two years = 125 + 135 = 250

Average = 250/2 = 125

Sum = 135 + 125 = 260

∴ Required sum is 260
