The total number of students surveyed by Omar in his school is 1000.
Here, we are given that Omar conducted a survey of some students in his school about their favorite color.
650 of those surveyed said their favorite color was blue.
Further, 65 percent of the students surveyed said their favorite color was blue.
Let the total number of students surveyed be x
Then, according to the given information,
65% of x is 650
Thus, we can form the following equation-
65/ 100 × x = 650
0.65x = 650
x = 650/ 0.65
x = 65000/ 65
x = 1000
Thus, the total number of students surveyed by Omar in his school is 1000.
