In a class, 40 percent are boys and the number of girls are 54. What is the number of boys in the class?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 36.
The percentage of boys in the class = 40%
The number of girls in the class = 54
The percentage of girls in the class = 100 - 40 = 60 %
Let the total number of students in the class be x .
0.6x = 54
x = 90
The number of boys = 90 - 54 = 36
