    Aakash's age is a factor of\[14\]. Next year his age will be a multiple of\[5\]. How old will he be in \[6\] years' time?

    A) \[15\,\,years\]                

    B)                     \[21\,\,years\]               

    C)                    \[14\,\,years\]                

    D)                     \[20\,\,years\]               

    Correct Answer: D

    Solution :

    Factors of \[14\] are \[1,\,\,2,\,\,7\] and\[14\]. Aakash's present age is a factor of\[14\] and his age the next year is a multiple of\[5\]. These conditions are satisfied for \[14\] as \[14\] is a factor of \[14\] and \[1\] more than\[14\] \[=15=\] multiple of\[5\]. Hence, in \[6\] years' time, the age of Aakash will be \[14+6=20\]years.
