Solution provided by Ekta27 has a slight error* (indicated below) but is the easier one (less number of steps) compared to the answer marked ‘Best’:
Splitting the process into individual steps:
The “Best Answer”:
1. Fill Cup A.
2. Keep aside. (For customer)
3. Fill Cup A again.
3. Keep aside (For customer)
4. Fill A again
5. Pour into B
6. Fill A again
7. Pour into B till B is full.
8. Pour remaining flour from A for customer.
Ekta’s answer (corrected):
1. Fill cup B.
2. Pour from cup B into cup A till A is full.
(* The sentence “Pack this for customer” after step 2 seems to imply that the qty filled in ‘A’ is to be packed, which is wrong.)
3. Keep aside (For customer)
4. Fill Cup B again.
5. Pack the contents of B for customer (along with the qty kept aside in step 3)
