Answer 2

Given: In a college there are 60% female students. 50 % of all the male students are in computer department. If there are total 62% students in computer department out of total 2400 students.

To find: The no. of female students who are in computer department.

Solution: The no. of female students who are in computer department is 1008.

If 60% of the total number of students are female, then 40% of the total number of students are male. Thus, the total number of male students are

$\frac{40}{100} * 2400 = 960$

Now, 50% of the male students are in the computer department. Hence, the number of male students that are in the computer department.

$\frac{50}{100} * 960 = 480$

Now, the total number of students that are in the computer department is 62% of 2400.

$\frac{62}{100} *2400 = 1488$

The count of 1488 includes 480 male students that are in the computer department and the others are female students. Thus, the number of female students in the computer department is

$1488 - 480 = 1008$

Therefore, the no. of female students who are in computer department is 1008.
