• For a journey of 16 km, the charges paid are Rs. 156 and for a journey of 24 km, the charges paid are Rs. 204.
  Additional charges for 8 kms = 204-156 = 48 Rs
  additional charge/km= 48/8 = Rs 6
  additional charge for 6 kms = 6*6 = Rs 36.
  
  total charges for 30 kms = 204 +36 = Rs 240

• Let the fixed charge be Rs. x and variable charge be Rs.y per km. Then,
  
  x + 16y = 156 ...(i) and
  
  x + 24y = 204 ...(ii)
  
  Solving (i) and (ii), we get: x = 60, y = 6.
  
  Therefore Cost of travelling 30 km = 60 + 30 y = Rs. (60 + 30 x 6) = Rs. 240.
