Looking at the label printed directly on the x-ray films, the patient information reads:

ANISHA KHATUN, 17 Y. F. (17-year-old female), R-26802, taken at ESIC Hospital, Joka, dated 07-08-20XX (the last digits of the year are cut off in the photo).

So the age recorded on this x-ray is 17 years. These are forearm AP and forearm LAT views showing the wrist/hand and elbow region respectively.

If you meant something different - like estimating bone age from the growth plates (epiphyses) visible on the film rather than the age printed on the label - let me know and I can walk through the skeletal maturity assessment.
