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:
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
