Question

in a graduate class of 200,40% are women and 1\5 become lecturers if the number of men who become lecturers is twice that of women calculate approximate percentage of men who become lecturer

Answer 1

Answer:

Percentage of Men who became lecturer's are = 40%

Step-by-step explanation:

In the question,

Total number of students in the class = 200

Percentage of Women in the class = 40%

Fraction of Women who became lecturer's = 1/5

Also,

Number of Men who became lecturer's are = Twice of Women = 2/5

So,

Number of Women in the class are,

=

Therefore, the number of Men in the class = Total students - No. of Women = 200 - 80 = 120

So,

Fraction of Men who became lecturer's are = 2/5

So,

Number of Men who became Lecturer's is given by,

Therefore, there are 48 Men who are lecturer's.

Percentage of Men who became lecturer's is,

$\frac{48}{120} \times 100$

Hence, the Percentage of Men who became lecturer's are = 40%

Answer 2

no. of woman = (200*40)/100

                      = 80

Women lecturer = (80*1/5)

                           = 16

Men lecturer = (16*2)

                    = 32

5 of men lecturer = (32/200)*100

                            =(32/2)

                           = 16%
