Consider a class of students with the following data: total students = 1000; students from State X = 200; students from State Y = 300. In addition, 40% of the students are female, of whom 50 are from State X and 180 are from State Y.
What is the percentage of students from States other than X and Y in the class?
A10%
B20%
C30%
D50% ✓ Correct
Correct answer: (D) 50%
Explanation
Students from other states are 1000 minus (200 plus 300) = 500; 500 over 1000 times 100 is 50%. Hence option D.
