Surely salary is very job dependant? Who have you spoken to? Examples of 300% difference in salary are common here. Sounds far fetched or indeed ridiculous....no. This is Qatar. It requires a certain suspension of disbelief.

Teenager also? Detail is what is required. By definition a "teen" of 13 will expect or want very different things than a 19 year old.

If you would care for advice that would be of help then do not couch your enquiries in such vagaries.
