Answer: 250 students. Step-by-step explanation: Let x students in 6th grade either purchased their lunch or brought their lunch from home on Monday. According to the question, 24% of the students purchased their lunch. ⇒ (100-24)% of the student brought their lunch from home. ⇒ 76 % of the student brought their lunch from home. But, Again according to the question, 190 students brought their lunch from home. ⇒ 76 % of x = 190
⇒ x = 250 Therefore, there are total 25 students in the 6th grade.
