These are definitely Soviet puzzles.

A collective farm was due to deliver its quota of grain to the state authorities. The management of the kolkhoz decided the trucks should arrive in the city at exactly 11 am. If the trucks traveled at 30 mph they would reach the city at 10 am; at 20 mph they would arrive at noon.

How far is the kolkhoz from the city, and how fast should the trucks travel to arrive at 11?

I'm not seeing much of a difference between "Amusing Problems" vs. "Difficult Problems". If anything, the "difficult" problems are a little easier to solve because they're more straightforward. Or maybe I'm just getting more used to the way Kordemsky thinks.

Deeply embarrassed that I got this one wrong:

An item is made from lead blanks in a lathe shop. Each blank suffices for 1 item. Lead shavings accumulated from making 6 items can be melted and made into a blank. How many items can be made from 36 blanks?
