To determine the number of phone calls received by Company C between 10:00 a.m. and 11:00 a.m., let’s examine each statement individually.
Statement (1)
This statement tells us that the number of calls received between 10:00 a.m. and 11:00 a.m. was 15% higher than the number of calls received in the previous hour. However, it does not give the actual number of calls received in the previous hour, so we can’t determine the exact number of calls between 10:00 a.m. and 11:00 a.m. based on this information alone.
Statement (1) alone is insufficient.
Statement (2)
This statement tells us that the average number of calls received per hour on that day was 24. However, without knowing how many calls were received in other specific hours or how many hours the company received calls, we cannot determine the exact number of calls received between 10:00 a.m. and 11:00 a.m.
Statement (2) alone is insufficient.
Combining Statements (1) and (2)
Even with both statements combined, we still lack the specific number of calls received in the preceding hour (9:00 a.m. to 10:00 a.m.), which is necessary to calculate the calls received between 10:00 a.m. and 11:00 a.m. with the 15% increase information.
Both statements together are insufficient.
Conclusion
The information provided is insufficient to determine the exact number of phone calls received by Company C between 10:00 a.m. and 11:00 a.m.
Answer: (E) The statements together are still not sufficient.
