The given bar diagram shows the number of students enrolled in Institutions A and B over the course of 5 years (2014 to 2018). What is the ratio of the average number of students enrolled in Institute B and the average number of students enrolled in Institute A during these years? Correct Answer 151: 125

Total number of students in Institute A = 160 + 280 + 300 + 250 + 260 = 1250

⇒ Average number of students in Institute A = 1250/5 = 250

Total number of students in Institute B = 225 + 360 + 375 + 325 + 225 = 1510

⇒ Average number of students in Institute B = 1510/5 = 302

∴ Required ratio = 302 : 250 = 151 : 125

Read the passage carefully and choose the best answer to each question out of the four alternatives.
In mid-2012 I completed my first massive online open course, or MOOC, the kind widely offered by Coursera, EdX, Udacity and so on in partnership with different educational institutions. It was on clinical trials and ethical practices, offered by Johns Hopkins, on Coursera. This was shortly before the MOOC sensation hit India, and when Coursera, which was founded by two Stanford professors, itself was just a few months old. The MOOC bug had bit me. The course Id completed was mainly designed for health care professionals who would be involved in actual clinical trials, not college students who had no prior knowledge of that area. I decided to enroll in the course because it was the only biology related course open at the time. However, I did see hope in that sometime in the future Id be able to get a glimpse of what classes are like in the hallowed halls of major educational institutions around the world. By early 2013, Coursera and EdX had partnered with so many educational institutions and expanded their course offerings to include everything from food and nutrition to Greek mythology to business, that I was spoilt for choice. I spent hours going through course catalogues and poring over course descriptions, almost delirious with excitement at the fact that I was actually going to be able to take classes offered by universities I had only dreamt of attending.
The course the author completed on MOOC was related to which subject?
