Answer:
Temperature of Wednesday = 300
Explanation:
Given:
Avg Temperature on Wednesday, Thursday and Friday = 250
Temperature on Thursday, Friday and Saturday = 240
temperature on Saturday = 270
To find:
what was the temperature on Wednesday?
Solution:
Since average temperature on Wednesday, Thursday and Friday is 250 which is computed by adding (sum) temperature of Wednesday, Thursday and Friday and dividing it by 3. So total temperature (sum) for these three days can be calculated by multiplying average value by 3 as:
250 * 3 = 750
Total Temperature (Wed, Thurs, Fri) = 750
Since average temperature on Thursday, Friday and Saturday is 240 which is computed by adding (sum) temperature of Thursday, Friday and Saturday and dividing it by 3. So total temperature (sum) for these three days can be calculated by multiplying average value by 3 as
240 * 3 = 720
Total Temperature (Thurs,Fri,Sat) = 720
Now
The difference between the temperature on Wednesday and Saturday is:
Total Temperature (Wed, Thurs, Fri) - Total Temperature (Thurs,Fri,Sat)
= 750 - 720
= 30
temperature on Saturday was 270, So
Temperature of Wednesday = 270 + 30
Temperature of Wednesday = 300
