<human>:  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?
<bot>: How many students like chess or basketball? ** The total percentage of students who said they like chess or basketball is 10% + 40% = 50%.
How many students like chess or basketball? ** So, 250 x 50/100 = <<250*50/100=125>>125 students like chess or basketball.
#### 125
