Question
Average temperature for a week is noted as 32D.C. But later it was realized that Monday temperature reading was taken as 30D.C instead of 16D.C. What is the true average temperature for the week?Options1530None of these1020
Solution
The problem can be solved in the following steps:
-
The average temperature for the week was initially calculated as 32 degrees Celsius. This means that the total temperature for the week (7 days) was 32 * 7 = 224 degrees Celsius.
-
It was later realized that the temperature for Monday was recorded as 30 degrees Celsius instead of the actual 16 degrees Celsius. This means that the total temperature calculated initially was 14 degrees more than the actual total temperature (30 - 16 = 14).
-
So, the correct total temperature for the week should be 224 - 14 = 210 degrees Celsius.
-
Therefore, the correct average temperature for the week would be the total temperature divided by the number of days. So, 210 / 7 = 30 degrees Celsius.
So, the correct answer is 30.

[39] The mean of the daily high temperatures for a 5-day period in a certain city was recorded as being 4.0°F. It was later determined that the high temperature for 1 of these 5 days was recorded incorrectly. If that day's high temperature was 2°F higher than originally recorded, what is the difference between the incorrectly recorded mean and the correct mean?
