Answer:
Ans... 10
Step-by-step explanation:
Total number of students = 50
students interested in mathematics = 80% of 50
= 80/100 * 50
= 40
so, the students interested in mathematics = 40
then, number of students not interested in mathematics = total number of students- students interested in mathematics.
= 50-40
= 10
Therefore , 10 students are not interested in mathematics.
