Question 55

The sum of the number of male and female students in an institute is 100. If the number of male students is $$x$$ , then the number of female students becomes $$x$$% of the total number of students. Find the number of male students.

Solution

Given, number of male students = $$x$$

Number of female students = $$x$$% of total students

Total number students = 100

$$\Rightarrow$$ $$x+\frac{x}{100}\times100=100$$

$$\Rightarrow$$ $$x+x=100$$

$$\Rightarrow$$ $$x=50$$

$$\therefore\ $$Number of male students = 50

Hence, the correct answer is Option B
