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?
a)240 gm
b) 250 gm
c) 260 gm
d) 230 gm
e) None.
Answer: Option a
ReplyDeleteExplanation:
Seven pieces consist of 6 smaller equal pieces and one half cake piece.
Weight of each small piece = 20 gm
So, total weight of the cake = 2 (20 * 6) = 240 gm
