Office on Time:

Tom and John have to be in their offices each day at 9 a.m..

To be on time, they have to catch the 8 o'clock bus; so they have to reach the bus stop 2 or 3 minutes before 8 o'clock.

Tom's watch is 10 minutes fast but he thinks it is 5 minutes slow.

John's watch is 5 minutes slow but he thinks it is 10 minutes fast.

Will both of them get to their offices on time?

Hawaii:

During his holidays in Hawaii George met a young man who told him, "The day before yesterday I was 25 and next year I will be 28."

Is it possible and if so what date did they meet?

These two problems were suggested by Lim Yi Jia from The Chinese High School, Singapore.
