It is not a luxurious salary but probably acceptable if you cut corners. For a family of 2+2, it will be very tight. Housing 7/8000, kid schooling for 2 3000, grocery 2000, car 2000. All of this takes out the 15000 Qr that you mentioned. Honestly, some will be very happy with this salary and for some it is a no go. It all depends on your individual needs.
