Explanation The stars present in the universe are very far away from one another. The light from the stars travel through the large distance and reaches the Earth. It takes one year for the light to cover the distance of one light year. The two stars of the same mass and their images are observed to have the same age means that the light from both the stars travel the same amount of distance to the Earth in the same time. Therefore, it is considered that the stars with the same age will also be at the same distance from the Earth. On the other hand, it can also be considered that for the image observed, the star which is at the larger distance from the Earth will be of more age as compared to the star closer to the Earth because the light from the farther star will take more time to reach the Earth...
