Answer 1

Answer:

21

Step-by-step explanation:

There are twenty-four persons facing north in a row. A is sixteenth from the right of E and C is fourth from the left of D. What is the

position of C from the right end if it is given that A is at one of the ends and E and D are neighbors?

Answer 2

The position of C from the right end is either 21 or 23.

Given:

There are twenty-four persons facing north in a row. A is sixteenth from the right of E and C is fourth from the left of D.

To Find:

The position of C from the right end if it is given that A is at one of the ends and E and D are neighbors.

Solution:

It is given that there is 24 person in the row and all of them are facing north. Also, it is given that A is 16th to the right of E so, A will be present at the right end because it is already given that A is at one ends. E will be in 16th position from the right end.

E and D are neighbors. So, D can either be on the immediate right or to the immediate left of E. Here two cases are formed.

Case 1: Consider D on the immediate right of E. Then C is at fourth to the left of D. The position of C in this case from the right end is 21.

Case 2: Consider D on the immediate left of E. Then C is at fourth to the left of D. The position of C in this case from the right end is 23.

Thus, the position of C from the right end is either 21 or 23.
