In a engineering college, students are divided in streams – Electronics, Electricals, Computer science, Mechanical, IT. Below the first pie chart gives the details of percentage break up in 2016 and 2017.  The number of students in 2016 and 2017 is 1640 and 2040 respectively.

1) What is the ratio of no. of students in Computer Science in 2016 to that of IT in 2017 ?

(a) 41 : 68     (b) 42 : 63     (c) 43 : 67    (d) 51 : 67      (e) None

2) If 12.5% and 25% of IT in 2016 and 2017 respectively include students from Biotech, then the number of Biotech students in 2017 is how much percent more than the number of biotech students in 2016?

(a) 150.20%     (b) 151.1%     (c) 162%   (d) 142%      (e) 148.78%

3) If in 2018, the percentage growth in the total no. of students is 40% over 2017 and the Mechanical students holds 37.5% weightage, then what is the growth rate in the no. of student of Mechanical in 2018 as compared to 2017?

(a) 112%     (b) 115%     (c) 95%   (d) 110%      (e) 112.5%
