Question 66

The bus fare between two cities is increased in the ratio 11:18. What would be the increase in the fare, if the original fare is Rs 550?

Solution

Let original fare = Rs. $$11x$$

=> New fare = Rs. $$18x$$

Also, original fare = $$550 = 11x$$

=> $$x = \frac{550}{11} = 50$$

$$\therefore$$ Increase in fare = $$18x - 11x = 7x $$

= $$7 \times 50 = Rs. 350$$
