Three guests were invited by Mr. Beaker to a party at the Science Mansion.
The party began at 7:00 P.M. However, at 9:00 P.M, Mr. Beaker’s favorite
microscope was stolen from his office! Each suspect entered his office at a
different time. Use the clues below to determine who stole the microscope.
• The people whose names do not start with the letter S did not enter the
office at 8:03.
• Ms. Hydrogen was the person who first noticed the missing microscope.
• Ms. Calcium entered soon after the start of the party.
• Mr. Sodium did not enter at 8:03
Based on the clues given, we can deduce the following:
1. Ms. Hydrogen noticed the missing microscope.
2. Ms. Calcium entered soon after the start of the party.
3. Mr. Sodium did not enter at 8:03.
Let's consider the possibilities:
1. If Ms. Hydrogen entered at 8:03, then she would not have noticed the missing microscope since she was the first to notice it. Therefore, Ms. Hydrogen did not enter at 8:03.
2. Ms. Calcium entered soon after the start of the party.
3. Mr. Sodium did not enter at 8:03, so Ms. Sodium must have entered at 8:03.
Based on this information, we can conclude:
1. Ms. Hydrogen did not enter at 8:03.
2. Ms. Calcium entered soon after the start of the party.
3. Mr. Sodium entered at 8:03.
This means that the thief is someone whose name starts with the letter S and entered the office at 8:03. Since Ms. Hydrogen was the first to notice the missing microscope, it cannot be her.
Therefore, the person who stole the microscope is Mr. Sodium.
