Question: Four subjects - Physics, Chemistry, Mathematics and Biology ...


Given Information:

- Four subjects - Physics, Chemistry, Mathematics, and Biology - were taught in four consecutive periods of one hour each starting from 8.00 a.m.

Statements:

I. Mathematics period ended at 10.00 a.m., which was preceded by Biology.
II. Physics was scheduled in the last period.
III. Mathematics period was immediately followed by Chemistry.

Explanation:

- From statement I, we know that Mathematics ended at 10.00 a.m. and was preceded by Biology. This means Biology was scheduled at 9.00 a.m.
- From statement III, we know that Mathematics was immediately followed by Chemistry. Since Mathematics ended at 10.00 a.m., Chemistry must have been scheduled at 11.00 a.m.
- Now, Physics was scheduled in the last period. Since Chemistry was scheduled at 11.00 a.m., Physics must have been scheduled at 12.00 p.m., the last period.

Therefore, the Chemistry period was scheduled at 11.00 a.m.

Conclusion:

The Chemistry period was scheduled at 11.00 a.m., according to the given statements.
