Download Solution PDFGiven:
Total number of students = 750
The number of students who like red and green colors only = 70% of 150 students
and The number of students who like red and blue colours only = 60% of 125 students
Formula used:
Average = (Sum of values)/(Number of values)
Calculation:
Total number of students who like only one colour = 109 + 150 + 125
⇒ 384 students
and Number of values = 3
Now, required average = 384/3
⇒ 128
∴ 128 is the average number of students who like only one color.
