Puzzle

I recently went to the shop and purchased 4 items.

Three of the items cost:

$1.50
$3.00
$4.00

There was quite a long queue, and as I was quite bored, I was playing with my pocket calculator whilst waiting.

Very curiously, the 4 prices added to the same number as I got when I multiplied the 4 prices together.

What was the price of the 4th item?

A Man in an Elevator

A man who lives on the tenth floor takes the elevator down to the first floor every morning and goes to work.

Otherwise, he goes to the seventh floor and walks up three flights of stairs to his apartment.

You are travelling down a country lane to a distant village. You reach a Y-junction in the road and find a pair of identical twin sisters standing there.

• One standing on the road to village and the other standing on the other Y-leg (of course, you don't know or see where each road leads).
• One of the sisters always tells the truth and the other always lies (of course, you don't know who is lying).
