Order and Ranking For SBI Clerk prelims

In this session we need to learn one main important formula to find the answers for order and ranking. i. e


T = L + R -1


Here T = Total number of persons
        L= Rank from the Left side
        R= Rank from the Right side


This formula is applicable only when we are saying about only one person in a row .

Ex: In a Row of 30 students . Raju is 14th from the Right . Then what is the Raju position from left ?


                     T= R+L -1
                   30= 14+L-1
                   L= 30-13 =17


Ex: In a Row  f children's ammu is sitting 12th from the right and 17th from the left . Then what is the total number of children's in a row?


                    T= 12+17-1
                    T=28
Ex: In a row of girls , swathi is 15^th from the Left and Ravi is 23^rd from the Right . If their positions are interchanged, then Swathi becomes 18^th from the Left. Then at what position will Ravi from the right?
Ans :
