Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 55
Calculations :
Total number of students enrolled for VC in institutes C in 2013, 2014 and 2017
⇒ 125 + 120 + 140
⇒ 385 ---- (1)
Total number of students enrolled in all the five institutes in 2018
⇒ 140 + 142 + 135 + 138 + 145
⇒ 700 ---- (2)
Using equation (1) and (2), we get
Percent of students enrolled = (385/700) × 100
⇒ 385/7
⇒ 55%
