No need for unnecessary answers please answer it with the correct answer Thank you :)

Answer 1

Answer:

no. of men = 90 and no. of women = 30

Step-by-step explanation:

Let no. of men = x

So, no. of men with beards = 3x/5

Let no. of women = y.

So, no. of women with long hair = 2y/3

3x/5 + 2y/3 + 46 = x + y

2x/5 + y/3 = 46

6x + 5y = 690 ....... (i)

Now, x + y = 120 (given)

So, 5x + 5y = 600 ....... (ii)

Subtracting (ii) from (i),

x = 90

y = 120 - 90 = 30

Therefore, no. of men = 90 and no. of women = 30
