Study the given table and answer the question that follows. The table gives marks scored by 5 students in 5 subjects in an exam.

‘What is the difference in total marks between the first and the fifth ranked students?

Given: ​

​$$\begin{array}{|c|c|c|c|c|c|c|}\hline\textbf{Subject} & \textbf{Jeeva} & \textbf{Justin} & \textbf{Hetal} & \textbf{Kuber} & \textbf{Alia} \\\hline\text{English} & 76 & 88 & 54 & 72 & 90 \\\hline\text{Maths} & 82 & 85 & 78 & 64 & 60 \\\hline\text{Science} & 69 & 80 & 82 & 80 & 75 \\\hline\text{History} & 70 & 72 & 76 & 83 & 80 \\\hline\text{Geography} & 86 & 90 & 85 & 80 & 73 \\ \hline\textbf{Total (Marks)} & 383 & 415 & 375 & 379 & 378 \\\hline\end{array}$$     

Solution: ​

As we can see in the given table that first ranked student is Justin,

 total marks of Justin =  415 

last ranked student is Hetal, 

total marks of Hetal = 375 .

Difference = 415 - 375 = 40
