Rohit stays far from the school and is good at Mathematics only while Kunal is weak in Mathematics only and stays close to the school. Neither of these two nor Ashish studies in class VI. One who is good at all the subjects studies in class V.
Which two boys are good at Mathematics ?
(I). Kunal stays close to school. So, the other three --- Rohit, Ashish and John stay far from the school.
(II). Rohit, Kunal and Ashish do not study in class VI. So, John studies in class VI.
Rohit and Kunal are not good at all subjects and John is in class VI. So, Ashish is good at all subjects and studies in class V.
Clearly, Rohit and Kunal study in class IV.
(III). Rohit is good at Mathematics, Kunal is weak in Mathematics. Ashish is good at all the subjects. Clearly, John is weak in all the subjects.
