The Riddle

There are 7 men. Each of these 7 men has 7 wives.

How many people are there in total?

Step-by-Step Solution

First, we calculate the number of wives:

  • 7 men × 7 wives per man = 49 wives

Next, each man and each wife has 7 children:

  • 7 wives × 7 children per wife = 49 children per man

Now, let’s find the total number of children:

  • 7 men × 49 children per man = 343 children

Finally, we add up all the people:

  • 7 men
  • 49 wives
  • 343 children

So, the total number of people is: 7 + 49 + 343 = 399

Thus, the answer to the riddle is 399 people. Do you have a different solution? Share your thoughts in the comments!
