I am not able to solve the following question, please help me solve it.
A cab driver got the rating as feedback from 20 customers on a given day which are as follows:
7 9 8 x 6 9 7 5 9 10 7 8 9 8 8 7 10 6 6 9
If the relative frequency of rating 7 is 0.25, then what is the value of x?

Assume the frequency of 7 t+0be y(since one element is missing, we can't take the given frequency)
Therefore y/20 = 0.25[20 is total frequency]
solving y=5. since there are only four 7's it means that x=7 and frequency of 7 is 5.
