Answer 1

There are two fathers and two sons

They were like

Grand Father   , Father      , Son

Here Father is Father for Son  & Son for Grand Father

Grandfather is Father for Father of Son

Hence

1   Grand Father     Father

2   Father                 Son

Here Father of Son is common  in both pairs

Hence total 3 people

Hence each buys a candy bar for 1 rupee.  and total for all the candy bar was Rs 3

Grand Father   , Father      , Son
