    A person travels a distance of 50 km. The amount he has to pay is

    A) Rs 155

    B) Rs 255

    C) Rs 355

    D) Rs 455

    Correct Answer: B

    Solution :

    On solving the above equations,
    we get
    \[\Rightarrow \,\,\,y=7\]
    \[\therefore \,\,\,x+10\times 7=75\]
    \[\Rightarrow \,\,\,\,x=75-70=5\]
    To travel a distance of 50 km, a person has to pay amount
    \[=x+50y=5+50\times 7\]
    =5+350=Rs 355
