Question 42

In a row of forty students, R is fifth from the right end and there are ten students between R and D. What is D’s position from the left end of the row?

Solution

The question does make it clear that R is on the right side as there are 4 people to his right and 10 people between R and D.

Hence, there are 15 people to the right of D.

So if x is the rank of D from left, 40 = x + 5 + 10 =>x= 25

So, there are 24 people to D's left. ie D is 25th from the left.
