I'll run a the Carfax if you can answer this question:

Two jars both exactly the same.

One bag of beans.

You tip four fifths of the beans into the first jar.
You tip the remaining fifth into the second jar

One jar- bean combo weighs 50 g
and the other jar-bean combo weighs 20 g…

Question…how much does one of jars alone weigh?

Show your reasoning.

You have ten minutes.

BTW, why in the hell would you want to buy a 1998 Ford Mustang with a salvage title?
