Correct option (d) Data are inadequate
Explanation:
As per question, Randhir obtained more marks than the total marks obtained by Kunal and Debu. So, marks of both Kunal and Debu individually must also be less than Randhir.
Randhir
Kunal,Debu
Total marks obtained by Kunal and Shankar are more than those of Randhir. So, the marks of Shankar can be more than or less than that of Randhir.
Sonal obtained more marks than Shankar, i.e. Sonal > Shankar
Neha obtained more marks than Randhir, i.e Neha > Randhir
It’* evident that we cannot tell for sure who amongst them attained the highest marks.
