Formula for percentile rank:
Percentile Rank = ( Cumulative frequency of the previous class of value + 1 2  frequency of the corresponding class Total frequency ) 100
In the given situation,
The given value is 45, which is lies in the age group 34-53.
The frequency of the class 34-53 is 5.
The cumulative frequency of the previous class (14-33) is 10.
And N=27
Therefore, the percentile rank for 45 is,
Percentie Rank = ( 10 + ( 1 2 5 ) 27 ) 100 = 46.30
