Question

In a row of persons, the position of rouza from the left side of the row is 27th and position of rouza from the right side of the row is 34th. Find the total number of students in the row?​

Answer 1

If ina any arrangement of 'n' number of students in a row if a student is at 'pth' position from LHS and 'qth' position from RHS then following relation holds :-

n + 1 = p + q ...(1)

now in your question the position of rouza from LHS i.e. p is p = 27 and that from RHS i.e. q is q = 34 now put above values in relation ...(1) we'ld get :-

n + 1 = 27 + 34

n + 1 = 61

n = 60

=> n =60.

i.e. there are 60 students in that row.

HOPE IT HELPS YOU.
