    Chair is $1600

    Table are 5 pieces

    Step-by-step explanation:

    Let the cost of a chair be x then for a table, it will be 5x since table cost 5 times as much as a chair.

    For $40000, chairs alone will be 40000/x while tables will be 40000/5x=8000/x

    The difference between these numbers is 20 hence

    40000/x-8000/x=20

    32000/x=20

    X=32000/20=1600

    The cost of a chair is $1600

    Table will be 5*1600=$8000

    The number bought will be proved as follows

    Chairs=40000/1600=25 pieces

    Tables=40000/8000=5 pieces

    Difference in number is 25-5=20
