    The product of the ages of Ankit and Nikita is 240. If twice the age of Nikita is more that Ankita's age by 4 years, the age of Nikita is

    A) 12 years 

    B)        15 years

    C) 10 years                       

    D) 20 years

    Correct Answer: A

    Solution :

    [a] Ankit's present age is x years. Nikita's age \[=\frac{240}{x}\] \[\Rightarrow \,2\times \frac{240}{x}-x=4\,or\,x=20\] \[\therefore \] Nikita's age \[=\frac{240}{20}=12.\]
