Aruna cut a cake into two halves and cuts one half into smaller pieces of equal size. Each of the small pieces is twenty grams in weight. If she has seven pieces of the cake in all with her, how heavy was the original cake ?	Choose the correct choice from the following options:
A) 120 grams B) 140 grams C) 240 grams D) 280 grams E) None of these
