No, it might have a percentile rank less than 70.

Step-by-step explanation:

Percentile is the measure indicating the the value below which a given percentage of observations of a group of observation falls.

For example 90 percentile in an exam means that the 90% of the people have scored below you in the exam.

70 percentile is the score below which 70% of the scores lie.

Now, it might be possible that less than 70% score lies below 82, in which case it can not be considered as 70th.

So, the score 82 might not be  necessarily be a passing score as it may have percentile score less than 70 percentile

hence, option 2 that is  

No, it might have a percentile rank less than 70. is correct
