I can solve it, but I will need to use calculator.

7 men times 7 wives = 49 wives + 7 men = 56

Children = Each wives 49 x 7 children = 343

343 + 56 = 399 people.

Let's break it down step by step:

1. Men:

There are 7 men


2. Wives:

Each man has 1 wife

So, 7 men × 1 wife = 7 wives


3. Children:

Each man and his wife have 7 children

So 7 couples × 7 children = 49 children



---

Now, add them up:

Men = 7

Wives = 7

Children = 49


Total people = 7 + 7 + 49 = 63

✅ Answer: 63 people
This is the only correct answer

Let's break this down carefully:

Given:

7 men, and each has 7 wives →
Total wives = 7 men × 7 wives = 49 wives

So total adults = 7 men + 49 wives = 56 adults

Each man and each wife have 7 children.


Now here's the trick:
It says each man and each wife have 7 children — this means:

Each of the 7 men has 7 children with each of his 7 wives
→ That’s 7 × 7 = 49 sets of children
And each set has 7 children
→ 49 × 7 = 343 children


So total number of people:

Men = 7

Wives = 49

Children = 343
→ Total = 7 + 49 + 343 = 399 people


✅ Answer: 399
Eggzactly.

That 49 wives not 7 wives, is where most people will miss it.

Let's break it down:
- 7 men + 7 wives = 14 adults
- Each of the 14 adults has 7 children, so:
- Total children = 14 x 7 = 98
- Total number of people = 14 adults + 98 children = 112

So, the total number of people is 112..

To those getting 63.
The question didn’t say each couple. It said each man and wife
63 is the right answer. You have committed error of double counting by assigning 7 children to each of the 14 adults. 7 children should simply be assigned to a couple each (a man and his wife) because no man or woman can have children individually without the other party.

7 men and their 7 wives = 14 adults.
Each man and his wife have 7 children together. Simply multiply a couple's 7 children by the 7 couples and you will get 49 children. Add the 49 children produced by all the couples (14 adults) and you will get 63.

Any other permutations is over analyzing of the question. No man can have 7 children without a wife in that scenario and no woman can have the 7 children without a husband too.

14 adults, with 49 children.

cos each pair of the adults have 7 children
You are correct!

63 people in total!

To find the total number of people, we need to count the men, their wives, and their children.
There are 7 men.
Each man has a wife, so there are 7 wives.
Each man and each woman (i.e., each couple) have 7 children. Since there are 7 couples, the total number of children is 7 couples × 7 children per couple = 49 children.
Now, we sum the number of men, wives, and children:
Men: 7
Wives: 7
Children: 49
Total number of people = 7 + 7 + 49 = 63.
Therefore, the total number of people is 63.

Lol. U calm down explain beautiful non sense. You see that phrase there? "WIFE" that's the trick. They didn't mention the men cheated. It's call logic. Same as there are 10 birds on a tree, a hunter shoots 1, how man birds will be left. U will say 10 - 1 =9. Cause they didn't say how many will be left on the tree grin grin grin
If you were logical enough, u should have known that giving birth occurs in pair. 1 man and 1 woman must mate b4 giving birth. The 14 u multiple with the 7 denotes that the 1 man gives birth the 1 woman too give births. Infact in biological terms they are hemophrodiles
Re: Can You Solve This Mathematics by 11doubledee: 10:49am On Jul 15, 2025
It all depends on how well you are able to comprehend the grammar.
Each wife plus children =8
7 wives for each man 8×7=56( wives and children for each man)
7 different men 56×7=392 (all wives and children)
Plus 7 grossly polygamous men. 392+7=399

Answered based on my own comprehension of the grammar.
Re: Can You Solve This Mathematics by jacobs2015: 10:49am On Jul 15, 2025
Why do we have people that don't pay attention to simple questions?

All responses here show how we Nigerians comprehend English, which is quite very poor.

Why is the "90% eliminated" not factored into the calculations? Or it's not part of the question?

I can see why people fail aptitude reasoning woefully.
Re: Can You Solve This Mathematics by Honestey: 10:49am On Jul 15, 2025
This one is more of understanding English than just mathematical calculation. For instance the statement " 7 men has 7 wives" isn't clear enough to attach each wife to each man.
7 men has 7 wives could mean 1 man has 7 wives but the remaining 6 men are singles. For this ambiguity I won't waste time calculating anything because no matter the answer someone gets, another person can always come up with a different one based on his understanding of the grammar.

7 men have 7 wives..most of u started failing from here..logically, one man with 7wives, they become 8 with out family yet..the wives nd men, thus, are 8×7..

Let's break down the problem step by step:


---

Given:

7 men

Each man has 7 wives
→ So total wives = 7 men × 7 wives = 49 wives


Now, each man and each wife has 7 children.

So:

Children per man = 7 → 7 men × 7 children = 49 children from the men

Children per wife = 7
→ 49 wives × 7 children = 343 children from the wives


Now let’s calculate total distinct people.

> 🚨 Important: Don't double count children. The way it's worded suggests each adult (man or wife) has 7 children, but the children are likely the same (shared). But the statement says each man AND each wife has 7 children. That implies each person (man or wife) has 7 different children.



So, this results in multiple distinct sets of children.

Let’s assume each person has their own 7 children, and those children are all unique.


---

Step-by-step:

Adults:

Men: 7

Wives: 49


Children:

Each man has 7 unique children → 7 × 7 = 49

Each wife has 7 unique children → 49 × 7 = 343


So total children = 49 + 343 = 392


---

Total number of people:

Men: 7

Wives: 49

Children: 392


➡️ Total = 7 + 49 + 392 = 448 people


---

✅ Final Answer: 448 people.

✅ Final Answer: 448 people.
You failed it when you ascribed 7 children to each man. Each man cannot have 7 children on their own, the 7 children for each wife covers the 7 children for each man.

In short each wife 7 children is the result of each man + each wife.
Re: Can You Solve This Mathematics by Donemmy(m): 10:54am On Jul 15, 2025
CORRECT. Thumb up for you.
7 Men have 7 wives ( 1 wife each )= 14 Adults.
Each Husband & Wife: 7 children.
Number of Children: 7*7= 49.
Number of people= 14 Adults+ 49 Children=63 people.
bammyllonaire:
Let's break it down step by step:

1. Men:

There are 7 men


2. Wives:

Each man has 1 wife

So, 7 men × 1 wife = 7 wives


3. Children:

Each man and his wife have 7 children

So 7 couples × 7 children = 49 children



---

Now, add them up:

Men = 7

Wives = 7

Children = 49


Total people = 7 + 7 + 49 = 63

Definitely a couple thing because men don't give birth to children.
Re: Can You Solve This Mathematics by MisteerConcord(m): 10:57am On Jul 15, 2025
Men: 7 men
Wives: 7 wives (one for each man)
Children:
Each man and each wife have 7 children, so:
Each couple (man and wife) has 7 children.
There are 7 couples, so the total number of children is 7 couples x 7 children/couple = 49 children.

Total Number of People:

1. Men: 7
2. Wives: 7
3. Children: 49

Total = 7 + 7 + 49 = 63
The total number of people is 63.
Re: Can You Solve This Mathematics by PDPdestroyer(m): 10:57am On Jul 15, 2025
The first sentence didn’t include the word “each” so it is safe to assume one man one wife, making a family 7 (1 man, 1 wife) = 14 individuals
Each of these 7 individual families had 7 children = 49 children
Answer is 14+49 =63

Re: Can You Solve This Mathematics by Noah94(m): 11:01am On Jul 15, 2025
The answer is 399 people.
This is a case of serious polygamy going on.
-All 7 men married 7 wives.
Each of the wives gave birth to 7 children, this means that in a family, there are 57 people: 1 man + 7women + 49 children = 57.
To get the total, we'll multiply 57 by 7 families, that would give us a total of 399 people.

14 adults, with 49 children.

cos each pair of the adults have 7 children
Absolutely correct. The question didn't say each man has 7 wives each, I don't know where they are seeing 49 wives. Each man and each wife has seven children simply means each family has 7 children. 7*7 = 49. Add this to the 14; men and women , this gives 63.

Each man and each wife have 7 children.


Study the English well

It says 'each man and wife ' 'have'

It doesn't say everyone of the men and and everyone of the wife has 7 children 'each'


It seeks to tell us that each couple ( by couple I mean man and wife) have a shared '7' children.


Now does that change the character of the question?


Or the number characters needed to post on nairaland?
