Charge paid for a journey of 10 km = Rs 85
Charge paid for a journey of 15 km = Rs 120
So, the charge paid for the distance from 10 km to 15 km
(Rs 120 - Rs 85) = Rs 35
The fare for a journey of 25 km
= charge paid for 10 km + charge paid for each of the next distance of 5 km
= 85 + 3 (35) = 85 + 10 = Rs 190
