Answer 1

Answer:

Aruna has total 7 pieces of cake. one is the half one and other 6 are the small pieces. the weight of the small piece is 20 grams so the weight of the 6 pieces will be 20×6=120 gram. the other one's weight also will be 120 gram. therefore she has a cake of weight 120+120=240 gram
