In a row of girls, Swati is 11^th from the right end. Manisha is 14^th to the left of Swati. If Manisha is 12^th from the left end, then find how many girls are in the row ?

36

Swati position from right = 11

 Manisha position from right =  11 + 14 = 25

 Manisha position from left =  12

total number of girls =left position + right position -1 (left and right position of same person)

 Total  =  25 + 12 – 1  = 36

So, correct answer is option (C).
