Direction: Study the given information carefully and answer the following questions.

There are a certain number of people who scored different marks in an exam 20, 27, 33, 38, 40, 43, 45 and 50 but not necessarily in the same order. They are sitting in a linear row facing south. We have information about some of them.

Three people sit between I and E who is immediate right of J. Number of persons between I and E are same as number of persons between E and F. E is in the middle of the row. F is fifth to the right of G. Two persons sit between H and I who is five places away from J. The sum of marks of K and I is equal to sum of marks scored by H and L. One among the four (i.e. K, I, H, L) scored the highest marks and one among the four scored the lowest marks. I does not score the highest. K is third from one of the extreme ends but is not sitting between F and G. K scored more marks than E but less than J. G is at one of the extreme end. L sits to the immediate left of K. The difference between the marks scored by H and F is equal to the difference between the marks scored by I and G.
