7 men have seven wives. each man and each wife have seven kids. how many people are there?
The correct answer and explanation is:
To calculate the total number of people in this scenario, we need to account for all the individuals mentioned: the men, their wives, and their children.
- Men: There are 7 men.
- Wives: Each man has 1 wife, and since there are 7 men, there are 7 wives.
- Children: Each man and each wife has 7 kids. Since there are 7 men and 7 wives, this gives a total of 14 people (7 men and 7 wives) who have children. Each of them has 7 kids, so the total number of children is: 14 people×7 kids=98 children14 \text{ people} \times 7 \text{ kids} = 98 \text{ children}
Now, adding these together:
- 7 men
- 7 wives
- 98 children
The total number of people is: 7 men+7 wives+98 children=112 people7 \text{ men} + 7 \text{ wives} + 98 \text{ children} = 112 \text{ people}
Thus, there are 112 people in total. This calculation includes all the men, their wives, and the children of each man and wife. The problem may initially sound complex, but breaking it down step by step allows for easy computation of the total number of individuals in the group.
