25-55+(85+65)=120
5!(factorial)=5*4*3*2*1=120
so,
25-55+(85+65)=120=5!
it's true.

If you read the question again, you will probably notice the slight trick used in this question.

25 - 55 + (85 + 65) = 25 - 55 + 150 = 120

Now, 120 is also equal to 5!

5! = 5 * 4 * 3 * 2 * 1 = 120
Yes, we were talking about 5! (factorial) and if you read the question, thats what is written there.

A spy wanted to get into a secret club for some information.

But to enter you had to know there’s a secret password.

He waits outside and spies on two members.

When Member 1 knocks on the door, the guard knocks back 6 times and the member replies with 3 knocks and he was let in.

When member 2 knocks on the door, the guard knocks 12 times and the member replies with 6 knocks and he was let in.

So the spy thought he had cracked the logic so he knocked on the door.

The guard knocked ten times and the spy replied with 5 knocks but he was not let in.

What was the correct secret password and what’s the logic behind it?

Suppose you’re on a game show, and you’re given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the doors, opens another door, say No. 3, which has a goat. He then says to you, “Do you want to pick door No. 2?” Is it to your advantage to switch your choice?

I have many feathers to help me fly.
I have a body and head, but I'm not alive.
It is your strength which determines how far I go.
You can hold me in your hand, but I'm never thrown.

What am I?
