ANSWER MUST BE OPTION D , AS WHEN WE SUBTRACT 5/8 FROM 4 THEN WE WILL GET 27/8 WHICH IS EQUAL TO 3 3/8. THE METHOD IS BY DOING CRISS-CROSS MULTIPLICATION.

I think it should be option C as , the question is asking how much is left with her when she has baked. She used 5/8 of the flour to bake and 5/8 of 4kg is 2 ½ kg . 4kg take away 2½ kg equals 1½ kg. So it should be option C.

(Master answer) the correct answer is C.

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.
