AI-generated answer

To find out how many of the over 50s are male, we need to follow these steps:

Step 1: Determine the total number of people in the village who are over 50.

To do this, we can set up the equation 7x + 3x = 300, where x represents the common factor between the two parts of the ratio. Solving this equation, we find that x = 30.

Step 2: Calculate the number of over 50s who are female.

Since 60% of the over 50s are female, we multiply the total number of over 50s (7x + 3x) by 0.60.

(7x + 3x) * 0.60 = 10x * 0.60 = 6x.

Substituting x = 30, we find that there are 6 * 30 = 180 over 50s who are female.

Step 3: Find the number of over 50s who are male.

We can subtract the number of over 50s who are female from the total number of over 50s to find the number of over 50s who are male.

Total over 50s - Over 50s who are female = Over 50s who are male.

(7x + 3x) - 6x = 4x.

Substituting x = 30, we find that there are 4 * 30 = 120 over 50s who are male.

Therefore, there are 120 over 50s who are male in the village.

Answer:

Step-by-step explanation: to get the number of over 50s and under 50s in the village, we take 7+3=10 and 300/10=30

so there are 30x7=210 over 50s and 30x3=90 under 50s in the village.

if 60% of the over 50s are female, than 40% of the over 50s are male (assuming all ppl are binary. for me there are only two genders)

40% of 210 is 84.

so 84 of the over 50s are male

i hope this helps. apologize for any mistakes in my work.
