Question

In a row of 40 children, R is 11th from the right and there are 15 children between R and M. What is M's position from the left end of the row? 

• A. 14th
• B. 15th
• C. 13th
• D. Can't be determined
• E.

Hint:

Always check whether the positions given in the problem make sense based on the total number of elements in the set.

Answer 1

The Correct Option is A

- Total number of children = 40. - R is 11th from the right, so R's position from the left is: \[ 40 - 11 + 1 = 30. \] - There are 15 children between R and M, so M is at the 30th + 15 + 1 = 46th position. However, since there are only 40 children, the solution cannot be determined in this case. Thus, the correct answer is (a) 14th.
