Solution: From Statement 1: We know Train X's speed (60 km/h), the distance (300 km), and that Train X left 30 minutes (or 0.5 hours) before Train Y. However, we don’t know Train Y's speed, which is necessary to calculate when they will meet. Therefore, Statement 1 alone is not sufficient. From Statement 2: We only know Train Y’s speed (80 km/h), but this alone does not give us enough information to determine when the two trains will meet. Statement 2 alone is not sufficient. Combining Statements 1 and 2: With Train X's speed (60 km/h) and Train Y's speed (80 km/h), and knowing Train X left 0.5 hours before Train Y, we can set up an equation based on their relative distance and speeds to determine when they will meet. Let the time taken after Train Y’s departure for the two trains to meet be t. Train X would have covered 60 * 0.5 = 30 km by the time Train Y departs. Now, the remaining distance is 300 - 30 = 270 km, which they cover together at a relative speed of 60 + 80 = 140 km/h. Thus, t = 270 / 140 = 1.93 hours. Therefore, both statements together are sufficient. Correct Answer: (c) Both statements together are sufficient, but neither alone is sufficient.
