16. Let the present age of B be x.

    \ Four years ago he was ( x - 4 ) years

    \ Four years ago A was 5 ( x - 4 ) years

    Eight years hence B will be ( x + 8 ) years

    Eight years hence A will be 3 ( x + 8 ) years

    Difference in A’ age 8 years hence and 4 years ago is 12.

    \ 3 ( x + 8 ) - 5 ( x - 4 ) = 12

    \ 3x + 24 - 5x + 20 = 12

    44 - 12 = 2x

    2x = 32

    x = 16

    Hence C.

17. 

    Hence B.
