Total = rank from top + rank from bottom - 1
Persons between = difference of ranks - 1

Write the direction beside every rank. Most errors happen when a top rank is accidentally treated as a bottom rank.

Practice example: In a queue of 117 people, Kavya is 42nd from the front. What is her position from the rear?

Solution: Kavya is 76th from the rear.

In a merit list, Dev is 18th from the top and 47th from the bottom. How many candidates are there in total?
In a queue, Nisha is 34th from the front and 29th from the rear. How many people are in the queue?
In a line of 64 persons, Asha is 21st from the front. What is her position from the back?

Now apply the trick on real questions

Use the shortcut above before solving these questions

Use total = rank from one side + rank from other side - 1 when the same person is ranked from both ends.

Tip: Subtract 1 because the same person is counted in both ranks.

Step 1

Total = 7 + 10 - 1.

Step 2

Total = 16.

Rule

Total persons = rank from one end + rank from other end - 1.

3-second trick

If both ranks refer to the same person, add and subtract one.

Trap to avoid

Do not forget the duplicated person.

Correct answer

16

Thinking path

Seven students are counted through the ranked student from the top.
Ten are counted through the same student from the bottom.
The ranked student is counted twice, so subtract one.

Final answer: 16

Why this is fast: The direct rank formula removes the need to draw the whole line.
