Answers
Answer:
Total no. of students = 1920
First we find out how many students don't have an imobile
60% students have imobile and 15% have both
So, Total 75% students have an imobile
25% students don't have an imobile
No. of Students who don't have an imobile = Total no. of students × Percentage of students who don't have an imobile / 100
= (1920 × 25)/100
= 480
Total no. of students who don't have an imobile are 480
Second we find out how many students don't have a blueberry
30% students have blueberry and 15% have both
So, Total 45% students have a blueberry
55% students don't have a blueberry
No. of Students who don't have an imobile = Total no. of students × Percentage of students who don't have a blueberry / 100
= (1920 × 55)/100
= 1056
Total no. of students who don't have a blueberry are 1056
