    Explanation:
    Let the fixed charges = Rs. x (for the first 5 km)
    and the additional charges = Rs. y /km
    As per the question,
    x + 5y = 350 ....(i)
    x + 20y = 800 ...(ii)
    On solving eqn. (i) and (ii), we get
    x = 200, y = 30
    ∴   Charge for a distance of 30 km.
    = x + 25y = 200 + 30 × 25 = Rs. 950
