    A man was assigned to find the average age of a class of 15 students. By mistake he included the 50-year-old teacher as well and hence the average went up by 3 years. Find the actual average age of the class.

    A)  5 years            

    B)    7 years            

    C)    2 years

    D)    3 years      

    E)  6 years

    Correct Answer: C

    Solution :

    Let the actual average age of the class of 15 students be x years. Now, according to the question, \[15x=16(x+3)-50\] or, \[15x=16x+48-50\] \[\therefore \]\[x=2\,years\]
