    A) 3 : 1

    C)  11 : 4

    D)  14 : 5

    Correct Answer: C

    Solution :

    Let man's age be 4x years, and son's age be x years. Then, \[4x\times x=196\]\[\Rightarrow \]\[{{x}^{2}}=49\]\[\Rightarrow \]\[x=7.\] Man's present age \[=(4\times 7)\]yr = 28 yr and       son's present age = 7 yr Required ratio \[=(28+5):(7+5)=33:12=11:4\]
