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 ?

D. 280 grams
E. None of these

• ANS C.240grams
  
  The seven pieces consist of 6 smaller equal pieces and one half cake piece.
  Weight of each small piece = 20 g.
  So, total weight of the cake = [2 x (20 x6)]g= 240 g.
