Nuts
.
Three
boys were given a bag of nuts as a Christmas present, and it was agreed
that they should be divided in proportion to their ages, which together
amounted to 17½ years.
Now the bag contained 770 nuts, and as often as Herbert took four
Robert took three, and as often as Herbert took six Christopher took
seven.
The puzzle is to find out how many nuts each had, and what were the
boys' respective ages.
