**Tips & Tricks to solve Order & Ranking Problems**

Some basic formulas to determine the positioning of a person:

**Left + Right = Total + 1****Left = Total + 1 – Right****Right = 1 + 1 – left****Total = left + Right**

**Formulas for vertical & Horizontal**

**Note:** The above formulas are only for a single person’s position

**FOR EXAMPLE:**

**In a row of 40 students, A is 13th from the left end, find the rank from right end. **

**Solution -: **Total = 40 students

A’s rank from right side = Total + 1 – left

= 40 – 13 + 1 = 27 + 1 =** 28 **

**In a row ‘P’ is 25th from left end, Q is 30th from right end. Find the total no. of students in all. **

**Solution -: **Can’t be Determined as there are more than 1 possibilities in this case

When total is not given and 2 persons positions from left and right are given, then answer is **Can’t be Determined**
