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?
Answer & explanation
Correct answer: option 3
Average number of students enrolled for VC in B in 2014 , 2015 & 2017
= \(\frac{132 + 138 + 135 }{3}\)
= \(\frac{405}{3}\)
= 135
Average number of students enrolled in institute E in 2013 and 2018
= \(\frac{105 + 145}{2}\)
= \(\frac{250}{2}\)
= 125
Required sum = 135 + 125 = 260
