Question

In a school of 500 students one fifth of the student passed in maths exam out of which 50 were girls. What % of boys passed in the maths exam.

Answer 1

total no. of student
$= 500$



no. of student passed in maths
$= \frac{1}{5} of \: total \: = \frac{1}{5} \times 500 = 100$
no. of girl passed in maths=50



hence no. of boys passed in exam


= no. of total student passed- no. of girls passed


$= 100 - 50$
therefore,


percentage


$= \frac{no \: of \: boys \: passed.....}{total \: no \: of \: student} \times 100$
$= \frac{50}{500} \times 100 = 10\%$
