Question

In a graduate class of 200 ,40% are women and 1/5 become lectures. If the number of men who become lectures is twice that of women.calculate approximate percentage of men who became lectures?

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,

= $\frac{40}{100}\times 200=80$

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,

$\frac{2}{5}\times 120=48$

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

Percentage of Men who became lecturer's is,

$\frac{48}{120}\times 100= 40\ percent$

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