Question

In a school of 1400 students, there are 420 girls. The percentage of boys in the school is _______ 

Answer 1

70

Explanation;

Hint:

Given total number of students in school = 1400

Number of girls in school = 420

∴ Number of boys in school = 1400 – 420 = 980

% of boys in school = `"Number of boys"/"Total number of students" xx 100`

= `980/1400 xx 100`

= `980/14`

= 70

% of boys = 70%
