What can be the least possible total marks scored by all of them together in LRDI section.
Explanation:
Arranging marks in descending order
Difference in marks between consecutively ranked students: E – C = 5 H – E = 10 B – H = 9 F – B = 5 D – F = 15 G – D = 6 A – G = 10
Since rank of all students changed after adding marks of LRDI section, hence C who had least marks in Quant section will not have least overall marks. ⇒ C will definitely get non-zero marks in LRDI section.
Since we have to minimize the total marks in LRDI section, we will ignore the highest difference in the marks.
For example: We have to increase C’s marks. We can either increase it by 6 marks to take C above E or increase it by 16 marks to take C above H. In the second case increase is very high, hence we will consider only 1st case.
∴ C gets 6 marks in LRDI section.
If H gets 15 marks in LRDI section he will move above F.
While, if D gets 17 marks in LRDI section he will move above A.
Total marks after above changes.
∴ Minimum total marks obtained in LRDI section = 6 + 15 + 17 = 38.
Hence, 38.
