A bus charges fixed amount and variable amount depending upon the distance covered. If the fixed amount is Rs. 152. For a journey of 54 km, the initial charges are Rs. 603. If the Bus Company increases the variable amount by Rs. 3. Find the new charges for a journey of 105 km.
Given,
Fixed amount = 152 = Rs. 225
Let the variable amount be x
According to question,
225 + 54 x = 603
54 x = 603 – 225 = 378
x = 7
⇒ Variable charge is increased by Rs. 3
⇒ New variable charge = Rs. (7 + 3) = Rs. 10
∴ Charges for 105 km = 225 + (105 × 10) = 225 + 1050 = 1275
