Hi Hersh,
We cannot assume that he/she worked 48 hours mon-sat. He/she COULD have, and then worked 6 hours Sunday.

BUT he/she could have also worked 46 hours, for example, mon-sat and 8 hours on Sunday.

Or 46.5 hours mon-sat and 7.5 Sunday or 47 hours mon-sat and 7 Sunday.

There is more than one possibility. Since the pay is different for each possibility, the statements combined are still insufficient.

We cannot assume that the employee's regular work week is Monday to Saturday in which case, according to statement (2), he/she worked 48 hours for 6 days and the remaining 6 hours were worked on Sunday proving that (1) & (2) together are sufficient?
