Math Puzzle: Can You Solve How Many Legs Are on the Bus with All These Cats?

Here is the Question

There are 7 girls on a bus. Each girl has 7 backpacks. In each backpack, there are 7 big cats. For every big cat, there are 7 little cats.

Question

How many legs are there on the bus?

Number of cats = 14 per backpack. Number of legs per backpack = 14 x 4 = 56. Each girl has 7 backpacks; hence, the number of legs per girl = 56 x 7 = 392. Therefore, as there are 7 girls, the number of legs of cats = 392 x 7 = 2744. Since 7 girls have 14 legs, the total number of legs = 2744 + 14 = 2758. Assumptions: there is nobody else on the bus other than 7 girls and the cats.

I got the answer:

1. As there are 7 girls, that means 7 x 2 = 14 legs.
2. Each girl has 7 backpacks, which means 7 x 7 = 49 backpacks.
3. Each backpack has 7 big cats, so 49 x 7 = 343 big cats.
4. 343 cats x 4 legs equals 343 x 4 = 1372 legs.
5. For every big cat, there are 7 little cats, which means 343 big cats x 7 = 2401 little cats.
6. 2401 little cats means 2401 x 4 = 9604 legs.
7. Final conclusion: 14 + 1372 + 9604 = 10990 (answer).

The above answer is incorrect.

Solution

Number of girls = 7, hence 14 legs.

Number of bags = 49. Each bag contains 7 large cats and 49 small cats (a total of 56 cats in each bag). Total cats = 56 * 49 = 2,744 cats. Total cat legs = 2,744 * 4 = 10,976. Overall legs = 10,976 plus 14 legs = 10,990 legs (assuming no one else is there in the bus apart from girls with backpacks).

My answer is right. I don't understand why she is saying it's wrong from her perspective. But Geetika, you have also given the answer in the same way as I did.

Are you talking about only the legs of 7 girls, 343 big cats, and 2401 small cats? What about the legs of the driver and other passengers (along with their backpacks, pets, and legs) on the bus? 樂

All the same, I could open the file.

Question: There are 7 girls on a bus. Each girl has 7 backpacks. In each backpack, there are 7 big cats. For every big cat, there are 7 little cats.

Calculation: Girls: 7
Backpacks: 7 x 7 = 49
Big cats: 49 x 7 = 343
Little cats: 343 x 7 = 2401

Total Legs Calculation: Legs = (343 + 2401) x 4 + 7 x 2 = 10,990

Qadir

Calculation of Total Legs on the Bus

Number of Girls: 7

Number of Backpacks: 7 * 7 = 49

Number of Big Cats: 49 * 7 = 343

Number of Little Cats: 343 * 7 = 2401

Therefore, number of cats' legs = (2401 + 343) * 4 = 10976

And number of girls' legs = 7 * 2 = 14

In other words, the total number of legs = (10976 + 14) = 10990
