The marks obtained by Sulabh in Science is equal to the average marks obtained by Neetu and Shyam in Science. If Sulabh obtained 35 marks in Science and the sum of marks obtained by all the three is 145, how much marks did Neetu obtain in Science?

Sulabh's marks (35) equals the average of Neetu and Shyam. Let Neetu = N and Shyam = S. Then (N + S)/2 = 35, so N + S = 70. Total of all three is 145, so 35 + N + S = 145, giving N + S = 110. But we also have N + S = 70 from the first equation. This inconsistency means the problem has no valid solution, and even if we ignore it, we can only find N + S, not N individually.
