Question

David cuts a bread into two equal pieces and cuts one half into smaller pieces of equal size. Each of the small pieces is twenty grams in weight. If he has seven pieces of the bread all with him, how heavy is the original cake?

Answer 1

Answer:

240 gm. If she has 7 pieces totally, it means that one of those pieces is the uncut half, and the other half is cut into 6 pieces. Each of those 6 pieces has a weight of 20 gm which totally weighs 6*20= 120gm. If one half is 120 gm, then so is the other.

Answer 2

Answer:

240

Step-by-step explanation:

7 pieces = 7 - 1 = 6 because one is uncut half

Each cut piece = 20 gm

∴ One half = 6 × 20 = 120 gm

Entire bread = 120+120 = 240 gm
