The given pie charts show the distribution of students of graduate and postgraduate levels in five different institutes, P, Q, R, S and T in a twon. Study the pie charts and answer the question that follows.
(i) Total number of students of graduate level in five different institutes = 12400
(ii) Total number of students of postgraduate level in five different institutes = 8000
The number of students in graduate level in institute S is approximately what percentage more than the number of students in post graduate level in institute S?
(correct to one decimal place)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 72.2%
The total number of students at the graduate level in the institute S = 12400 × 20/100 = 2480
The total number of students at the post graduate level in the institute S = 8000 × 18/100 = 1440
The required percentage = (2480 - 1440)/1440 × 100 = 72.2%
