S safeer

Let the prise of the chair be x then the prise of table is 20x/8 =2.5x

Therefore prise of 30 chair+4 tables that is  

\\30x+4\times2.5x=8000\\\ that\ is\ 40x=8000 \ or \ x=200

That is prise of the chair is 200. Therefore the price of the table is 

2.5\times200=500

Therefore 12 chairs and 3 tables cost

12\times200+3\times500=3900
