Question

in a graduate class of 200, 40% are women and 1/5 become lecturers if the number of men who became lecturers is twice that of women, calculate approximent percentage of men who became lecturers​

Answer 1

Answer:

27%

Step-by-step explanation:

Number of women = 40% of 200 = 80

Number of men = 200 - 80 = 120

Number of women lectures = 

1515

 of 80 = 16

Number of men lectures = 16 × 2 = 32

∴ Required percentage :

=(32120×100)%=803%=2623%≈27%

Answer 2

$\red{\textbf{Answer :- 27}}$

Step-by-step explanation:

$\red{\textbf{Given :-}}$

$\textsf{Number of women = 40 of 200 = 80}$

$\textsf{Number of men = 200 - 80 = 120}$

$\textsf{Number of women lectures =}$$\LARGE \frac{1}{5}$

$\textsf{of 80 = 16}$

$\textsf{Number of men lectures = 16 × 2 = 32}$

$\textsf{∴ Required percentage :}$

$= ( \LARGE\frac{32}{120} \small \times 100)$

$= \LARGE \frac{80}{3}$

$= 26 \LARGE\frac{2}{3}$

$\textsf{≈ 27 }$%

$\textsf{so ,percentage of men who became lecturers}$

$\textsf{is 27 }$%

$\blue{\textbf{More information :-}}$

• a percentage is a number or ratio that represents a fraction of 100.

• $\Large \textsf{percentage difference :-}$

$= ( \LARGE\frac{|V_{1} - V_{2}|}{(V_{1} + V_{2})/2} \small \times 100)$
