Produce a product (Posted on 2012-01-09) Difficulty: 1 of 5
A certain number N divided by one more than itself yields one fifth.
Another number M divided by one more than itself yields one fifth of itself.
It is quite easy to find the product M*N.

Try to do it " by heart" i.e. no calc, no pen, no paper.
