b) Are there any students who scored equal marks?

c) Who got least aggregate marks?

d) How much marks were scored by roll no. 4?

$$\begin{array}{cccc}RollNo.& Maths& Physics& Chemistry\\ 1& 67& 78& 67\\ 2& 57& 78& 75\\ 3& 78& 64& 72\\ 4& 84& 60& 69\\ 5& 69& 70& 73\end{array}$$

Answer 1

Each option: 1 Mark

Marks scored by roll no. 1 = 67 +78 + 67 = 212

Marks scored by roll no. 2 = 57 +78 +75 = 210

Marks scored by roll no.3 = 78 + 64 + 72 = 214

Marks scored by roll no. 4 = 84 + 60 + 69 = 213

Marks scored by roll no.5 = 69 + 70 + 73 = 212

a) Maximum marks is scored by roll no. 3 = 214

b) Yes, marks scored by both roll numbers 1 and roll no. 5 are the same = 212

c) Least marks is scored by roll no. 2 = 210

d) Aggregate marks scored by roll no. 4 is 213
