  1. Don't know the pqr format, but the argument is true.

    3 states that he failed, 1 states that he could not have failed had he studied, therefore, he did not study.

    2 states that if he did anything other that playing basketball, he would be studying. Because we already know he was not studying, he could have done nothing other than playing basketball. Basketball being the only thing other than studying he could have done.

    Hope it helps.


  2. he failed mathematics

    so from 1 he did not study

    so from 2 he did play basketball
