Pune taxi services has a fixed charge plus a variable charge based on the distance covered. For travelling 10km the total fare paid by Somu is Rs.150 and for a journey of 15km the total fare paid by Ramu is RS220. Then Tomy will pay _as the total fare for travelling a distance of 25 km.

Let the fixed charge be Rs. x and variable charge/km is Rs. y.

As per the question,

x + 10y= 150 and x+ 15y = 220

On solving both the equations, we get 5y = 220-150= 70

y = Rs. 14/km and x = Rs. 10

Charge for 25 km = x+ 25y 

= 10+25*14 = Rs. 360

C is the correct answer.
