total temperature of Monday Tuesday Wednesday and Thursday = 4× 48
= 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.

                     48=\frac{(Temp. for Monday + Temp. for Tuesday+ Temp.for Wednesday + Temp.for Thursday)}{4}         Temp. for  Monday + Temp. for Tuesday+ Temp.for  Wednesday + Temp.for Thursday = 48\times4  

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.

                           46=\frac{ (Temp. for Tuesday+ Temp.for Wednesday + Temp.for Thursday+Temp.for Friday)}{4}          

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 = 192-184=8

   

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  =42-8

Temp.for Friday      = 34

Thus, Temperature on  Friday  was   34 deg.
