Answer: Option B
:
B
We can calculate the total points scored by each candidate in all the tests together using the formula,
Total points = GPA * 5.
Ravi's score in tests 2, 3 and 5 = 23 - 1 - 7 = 15
From the conditions given in the data, Ravi scored 1, 4, 10 or 1, 7, 7 or 4, 4 7 in tests 2, 3 and 5 respectively.
Calculating, in a similar manner, we get that Pankaj scored 0, 1, 10 or 0, 4, 7 in tests 3, 4 and 5 respectively.
Also, Akshay scored 1, 10, 10 or 4, 7, 10 in tests 2, 3 and 5 respectively.
Continuing this way, we get the table below.
$\begin{array}{ccccccc}Name& Test1& Test2& Test3& Test4& Test5& TotalPoints\\ Manish& 0& 1& 4& 7& 10& 22\\ Alok& 0& 0& 4& 7& 7& 18\\ Vijay& 0& 0& 1& 10& 10& 21\\ Ravi& 1& \frac{1}{4}& \frac{4}{7}& 7& \frac{7}{10}& 23\\ Raj& 0& 1& 1& 7& 10& 19\\ Mohit& 1& 1& 7& 7& 10& 26\\ Sagar& 1& 4& 7& 10& 10& 32\\ Rakesh& 0& 1& 7& 7& 10& 25\\ Shekhar& 4& 7& 10& 10& 10& 41\\ Pankaj& 0& 0& 0& \frac{1}{4}& \frac{7}{10}& 11\\ Akshay& 0& \frac{1}{4}& \frac{7}{10}& 10& 10& 31\\ Paresh& 0& 4& \frac{4}{7}& \frac{10}{7}& 10& 28\\ Salman& 0& 1& 7& 10& 10& 28\\ Vinod& 4& 4& 7& 10& 10& 35\\ Neeraj& 0& 1& 1& 4& 10& 16\end{array}$
Out of 15 candidates, except Alok, Ravi and Pankaj, all the others scored 10 points or A+ grade in test 5. Hence , [b].
