The average temperature for wednesday,Thursday, friday was 40 degree C. The average for thursday, friday and saturday was 41 degree C. if temperature on saturday was 42 degree C, what was the temperature on wednesday?

Answer 1

Answer:

39°C

Step-by-step explanation:

Average temperature for Wednesday, Thursday and Friday = 40° C

Total temperature = 3 × 40 = 120° C

Average temperature for Thursday, Friday and Saturday = 41° C

Total temperature = 41 × 3 = 123° C

Temperature on Saturday = 42° C

Now,

(Thursday + Friday + Saturday) - (Wednesday + Thursday + Friday) = 123 - 120;

Saturday - Wednesday = 3

Wednesday = 42 - 3 = 39° C
