the average temperature for monday, tuesday, wednesday and thursday was 48 degrees and for tuesday, wednesday, thursday and friday was 46 degrees. if the temperature on monday was 42 degrees. find the temperature on friday?
Answers
= 192
total temperature of Tuesday Wednesday Thursday and Friday = 4×46
= 184
total temperature of Tuesday Wednesday and Thursday = 192 - 42
= 150
the temperature of Friday = 184 - 150
= 34
The temperature on Friday was 34 deg.
Step-by-step explanation:
Given:
The average of temperature on monday, tuesday, wednesday and thursday was 48 deg.
The average of temperature for tuesday, wednesday, thursday and friday was found 46 deg.
The temperature on monday was 42 deg.
To Find:
The temperature on Friday.
Formula Used:
Average temperature = Total of Temperature of various days/ Total of number of days -------- formula no.01
Solution:
As given - The average of temp. for monday, tuesday, wednesday and thursday was found 48 deg.
Applying formula no.01.
Average Temperature = (Temp. for Monday + Temp. for Tuesday+ Temp. for Wednesday + Temp.for Thursday)/Total number of days.
Temp. for Monday + Temp. for Tuesday+ Temp.for Wednesday + Temp.for Thursday
Temp. for Monday + Temp. for Tuesday+ Temp.for Wednesday + Temp.for Thursday = 192 -------------------------------------------- equation no.01
As given - The average of temperature for tuesday, wednesday, thursday and friday was found 46 degrees.
Applying formula no.01.
Average Temperature = (Temp. for Tuesday+ Temp.for Wednesday + Temp.for Thursday+Temp.for Friday) /Total number of days.
Temp. for Tuesday+ Temp.for Wednesday + Temp.for Thursday+Temp.for Friday =184 --------- equation no.02.
Subtraction equation no. 02 form equation 01, we get.
Temp. of Monday - Temp.of Friday
Temp.. for Monday - Temp.for Friday= 8 ----------------------- equation no.03
As given- The temperature on monday was 42 degrees.
Temp.on Monday = 42
Putting this value of Temp. on Monday to equation no. 03, we get.
42- Temp.for Friday= 8
Temp.for Friday
Temp.for Friday = 34
Thus, Temperature on Friday was 34 deg.
