The following pie charts show the number of students studying in different departments of an institute during the acaedemic years 2019 and 2020. The total number of students was 2000 and 2400, respectively, in academic years 2019 and 2020.
What is the ratio of Commerce and computer Science students taken together in 2019 to Engineering and Medical Students taken together in 2020?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 65 : 44
Commerce students in 2019 = 25% of 2000 = 500
Computer science students in 2019 = 14% of 2000 = 280
Total students = 780
Engineering students in 2020 = 12% of 2400 = 288
Medical students in 2020 = 10% of 2400 = 240
Total students = 288 + 240 = 528
Ratio = 780 : 528 = 65 : 44
