Question 87

The bus fare between two cities is increased in the ratio 17:20. Find the increase in the fare, if the original fare is Rs. 425

Solution

Let original fare = Rs. $$17x$$

=> New fare = Rs. $$20x$$

Also, original fare = $$425 = 17x$$

=> $$x = \frac{425}{17} = 25$$

$$\therefore$$ Increase in fare = $$20x - 17x = 3x $$

= $$3 \times 25 = Rs. 75$$

=> Ans - (D)
