Solve the riddle and you can open it

How to open attached file ?

There is a bus with 7 girls

Each girl has 7 bags .

In each bag, there are 7 big cats

Each big cat has 7 little cats.

Each cat has 4 legs .

Question: How many legs are present in the bus?

Number of legs is the password to open the attached file.

If you open the file, write your name on the list inside, and send
this email to your friends to let them solve it

this is the modified version. the original one has a lot of bull about how only geniuses can open the file. its pretty lame. im sure even my primary skul cousin can solve it. but anyone who wants it tell me i can send it to u.
