• A. ₹$240$
• B. ₹$245$
• C. ₹$204$
• D. ₹$256$

Answer 1

The correct option is D

₹$256$

Finding the cost in covering $1km$:

A rail journey of $50km$ costs ₹$160$

therefore, the cost in covering $1km=₹\frac{160}{50}$

By unitary the method,

$80km=80\times \frac{160}{50}=₹256$

Hence, the cost of the journey of $80kmis₹256$
