No, at this point in the story he would not have wanted another match.
Two reasons from the text support this. First, Surya was clearly the better player — “on Friday, at the badminton court, Surya was a real phenomenon. He won points again and again.” Prabhat knew he had not really won; a second match would very likely expose him. Second, Prabhat’s rule for himself was fixed: “He would take part only when he was sure of winning.” He could not be sure of winning against Surya.
Notice that it is Surya, the loser on paper, who cheerfully suggests it: “It’s been fun. We should play again some other time.” The offer comes from the boy who did not mind losing.
Tip: A ‘Do you think…?’ question always has two halves — the opinion and the reason. Answer both, and take your reason from the story.
