12% of all students are from Chennai. What is the largest possible percentage of economics students that can be from Chennai, rounded off to the nearest integer?
Explanation:
Consider the solution to previous question.
Total number of students = 1250
12% of these are from Chennai = 12% of 1250 = 125 + 25 = 150
Out of these 150 students 40 are definitely majoring in Physics.
∴ Maximum students from Chennai who can major in Economics = 150 – 40 = 110.
Total number of students in Economics = 12% of 1250 = 150.
∴ Highest possible percentage of Economics students that can be from Chennai = 110/150 × 100% = 73.33% ≈ 73%.
Hence, option (d).
