Question

The mean age of 15 men in a town is 62 years and the mean age of 10 women is 52 years. Find the mean age of the people in the town.​

Answer 1

When we produce a good by exploiting natural resources, it is an activity of primary sector. This is because it forms the base for all other products that we subsequently make. Since most of the natural products are from agriculture, dairy, fishing, forestry, this sector is also called agriculture and related sector.

Answer 2

Step-by-step explanation:

Let total no. of people in the group be 100 and out of them x are men

i.e no of women = 100−x.

Mean age = no of peoplesum of ages in the group

Total sum = sum of ages of men + sum of ages of women

⇒100×25=x×26+(100−x)×21

⇒x=80

Hence, the percentage of men and women in the group is 80,20 respectively
