Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 26.15%
The average number of students enrolled in institute A during 2014, 2016 and 2018 = (160 + 300 + 260 )/3 = 240.
The number of students enrolled in institute B during 2017 = 325.
Required % = (325 - 240)/325 × 100 = 26.15 %.
