Question

Average temperature from 9th to 16th of a month is 30 o c and that from 10th to 17th is 31 o

c. What is the temperature on 17th, if temperature on 9th is 35 o c ?

Answer 1

Answer: 43°c

Explanation:  

Total temperature from 9th to 16th of a month = 8 ×30°c = 240°c

And 10th to 17th = 8 × 31°c = 248°c

Temperature of 17th

                          = 35°c + (248°c - 240°c)

                          = 35°c + 8°c

                          = 43°c
