• A. 15th
• B. 5th
• C. 30th
• D. Data inadequate
• E. None of these

Answer 1

Answer: (D)

Data inadequate

Case I: In a row of 35 children, M is 15th from the right end.

R's position from the right, 15 + 10 + 1 = 26th
R is 26th positions from the right.
Position of R from the left end of the row.
= (35 - 26) + 1 = 9 + 1 = 10th
Case II:

Position of R from the left,
= 35 - 5 + 1
= 30 + 1 = 31st
