Solution & Step-by-step Explanation

Let the original Bus fare be 4 x and Train fare be 5 x . * New Bus fare after a 10% increase: 4 x \times (1 + \frac{10}{100}) = 4 x \times 1.1 = 4.4 x * New Train fare after a 20% increase: 5 x \times (1 + \frac{20}{100}) = 5 x \times 1.2 = 6.0 x Now, calculate the new ratio: New Ratio = \frac{4.4 x}{6.0 x} = \frac{44}{60} = \frac{11}{15} So, the new ratio is 11 : 15 .
