A) \[{{12}^{o}}C\]
B) \[{{30}^{o}}C\]
C) \[{{46}^{o}}C\]
D) \[{{22}^{o}}C\]
Correct Answer: B
Solution :
Initial temperature on Sunday \[={{34}^{o}}C\] Total fall in temperature by \[2:00\,\,a.m.\] on Monday \[={{9}^{o}}C+{{3}^{o}}C={{12}^{o}}C\] The temperature at \[2:00\,\,a.m.\] On Monday\[={{34}^{o}}C-{{12}^{o}}C={{22}^{o}}C\] The temperature rose by \[{{8}^{o}}C\] by \[8:00\,\,a.m.\]on Monday. \[\therefore \]Final temperature at \[8:00\,\,a.m.\] on Monday. \[={{22}^{o}}C+{{8}^{o}}C={{30}^{o}}C\]You need to login to perform this action.
