I appreciate the answer given by C Sri Vidya Rajagopalan.
There is an another version of the three statements from the book, "The Life of Ramanujacharya" by Naimisaranya Das, published by the Vaisnava Educational Alternative (VEDA) in 1989.
"Very well" Yamunacharya responded, "I will put three propositions before you, and, if you can refute them, I shall accept defeat." Kolahala agreed and prepared to refute Yamunacharya's statements. "My first proposition is this" Yamunacharya spoke out clearly and boldly, "that your mother is not a barren woman. Refute this if you can."
Hearing this, Kolahala remained silent. "Had my mother been barren, my birth would not have been possible" he thought. "How can I refute this statement" Seeing Kolahala as silent as a dumb man, all the courtiers were astonished. Although the great pandita tried to conceal his anxiety, he could not prevent a flush from crossing his cheeks.
Yamunacharya spoke again, "Sir, if in spite of your all-conquering intelligence you are unable to refute my first proposition, then please hear my second. It is this, that the Pandya king is supremely righteous. Refute this if you can." On hearing this Kolahala, was deeply disturbed, sensing his imminent defeat. With the king seated there in front of him, how could he deny the boy's statement? Again he remained silent, the color draining from his face as he was scarcely able to control his anger.
Yamunacharya spoke again, "Here is my third proposition - that the queen of the Pandya king is as chaste and faithful to her husband as was Savitri. Refute this if you can."
Seeing how he had once again been trapped by the intelligent boy, Kolahala could no longer restrain his anger. "You rascal" he screamed, "how can any loyal subject say that his king is unrighteous or his queen unfaithful to her husband? It is true I have not replied to your statements, but that does not mean I am defeated. First you must refute your own propositions, and, if you cannot, you should be put to death, for the implications of you words are treason against your king and queen."
When Kolahala shouted out these words, all his disciples and supporters cheered; but all those who favored Yamunacharya cried, "No, Kolahala is defeated. He is simply letting forth his anger, because he could not refute the statements of Yamunacharya as he promised to do".
Thus an argument broke out in the palace, but in the midst of the contention Yamunacharya quieted them all by saying, "Please stop this argument, for it is unnecessary. I shall refute all my propositions one by one. Please hear me." At this everyone fell silent and turned their attention to Yamunacharya, wondering how he could possibly do this and yet not offend the king and queen.
"My first statement" he continued,"was that our great pandita's mother was not a barren woman. However, it is stated in the Manu-samhita that a woman who has only one child is to be considered barren. As your mother gave birth to only one son, even though he is a man of such merit as yourself, according to the sastra, she must be considered barren. Secondly, I stated that the king of the Pandyas is a most righteous man. However, the Manu-samhita states that a king enjoys the benefit of one sixth of the religious acts of his subjects, but also has to bear the burden of one sixth of their sinful deeds. Because in the present age of Kali men are more prone toward sinfulness than piety, it must follow that our king, although flawless in his own character, is bearing a heavy burden of unrighteousness. And now to my third proposition, which stated that our queen is as chaste and faithful as was Savitri. But again, if we consult the laws of Manu, it is said that the king is the representative of Agni, Vayu, Surya, Chandra, Yama, Kuvera, Varuna, and Indra. Therefore, the queen is married not to just one man, but to these eight demigods as well. So how can it be said that she is chaste?"
On hearing these wonderful answers, all the people were filled with amazement, and the queen joyfully cried out, "Ala-bandara! Ala-bandara! He has conquered! He has conquered!"
