Question
The pie chart given below shows the number of students
in seven different institutes in a town. Total number of students in all the seven institutes is 168000. The number of students in a particular institute is shown as a percent of total number of students in all these seven institutes. Which of the following statement(s) is/are correct? I. Number of students in Institute A and B together is 20160 more than the number of students in institute F and G together. II. Ratio of number of students in institute A to the number of students in institute C is 6 : 5 respectively.Solution
From statement I (15% + 13%) - (9% + 7%) = 28% - 16% = 12% = 12 × (168000/100) = 1680 × 12 = 20160 So, statement I is correct From statement II The ratio of number of student in A and C = (15%/18%) = (5/6) So, statement II is incorrect
