Question

The average maximum temperature for 7 days from the 12th September to 18th September is ${35}^{\circ }C$ and that for 7 days from 13th to 19th September is ${34}^{\circ }C$. From this we can conclude that

• A. Maximum temperature on 19th is $1^{\circ }C$ less than that for 12th September
• B. Maximum temperature on 12th is $1^{\circ }C$ less than that for 19th September
• C. Maximum temperature on 19th is $7^{\circ }C$ less than that for 12th September
• D. None of the above

Answer 1

Answer: (C)

Maximum temperature on 19th is $7^{\circ }C$ less than that for 12th September

The average maximum temp from 12th sept to 18th sept is 35 and The average maximum temp from 13th sept to 19th sept is 34

Then total temp from 12th sept to 18th sept =35$\times$7=245

And total temp from 13th sept to 19th sept =34$\times$7=238

Then diff=245-238=7

So Maximum temperature on 12th is7 ${}^0$less than that for 19th September
