    Explanation:
    Let the fare from station P to station Q is Rs. x and the fare from station P to station R is Rs. y.
    By given condition, x + y = 42                .....(i)
    and 5x + 10y = 350                                 .... (ii)
    On solving Eqs. (i) and (ii), we get
    x = 14 and y = 28
    Hence, fare from station P to station Q is Rs. 14.
