    Answer:

    Therefore 975 is divisible by 3 and 5 but not by 6

    Step-by-step explanation:

    Divisibility Test of 3=Sum of digits should be divisible by 3

    975-9+7+5=21

    21 is divisible by 3(7*3)

    therefore 975 is divisible by 3

    Divisibility test of 6= should be divisible by both 2 and 3

    Divisibility of 2= last digit should be even

    975 is not divisible by 2

    975 is divisible by 3

    Hence 975 is not divisible by 6

    Divisibility test of 5=Last digit should be 5 or 0

    975 is divisible by 5(Since last digit is 5)
