       The average temperature of first three days \[22{}^\circ C\] and of the next three days is \[24{}^\circ C\]. If the average temperature of the whole is\[23{}^\circ C,\]what is the temperature of the last day of that week?  

    A)  \[24.6{}^\circ C\]                    

    B)  \[26.5{}^\circ C\]

    C)  \[28.5{}^\circ C\]                    

    D)  \[32.4{}^\circ C\]

    Correct Answer: B

    Solution :

    Sum of temperature of first 3 days \[=22{}^\circ C\times 3=66{}^\circ C\] Sum of temperature of last 3 days \[=24{}^\circ C\times 3=72{}^\circ C\] Sum of temperature of whole week \[=23.5{}^\circ C\times 7=164.5{}^\circ C\]             The temperature of the day                         \[=(164.5-66-72){}^\circ C=26.5{}^\circ C\]
