Answer 1

I didn't understand your question properly.

But, until I understood. The answer for this question is as follows:

Total pieces of the cake - 12 part

Sara ate - 1 part

Anju ate - 2 part

12 part - (1 part + 2 part)

12 part - (3 part)

9 part

∴The mother ate 9 parts of the cake

                                           

Answer 2

Answer-
Total pieces- 12
Total amount of pieces Sara ate- 1
Total amount of pieces Anju ate- 2
Total amount of pieces their mother ate- 12-(2+1)=12-3=9
So, the mother ate 9 pieces of the cake.
