In a survey about the student's favorite sports, 40% said they like basketball, 10% like chess, 28% like soccer, and the rest said they like badminton. If 250 students were interviewed, how many students identified chess or basketball as their favorite sport?
Step-by-step reasoning process: The total percentage of students who said they like chess or basketball is 10% + 40% = 50%. So, 250 x 50 / 100 = 125 students like chess or basketball.
The answer is 125.
