    Answer:

    The number of Three digit natural numbers which are divisible by 11 is 81

    Step-by-step explanation:

    First three digit natural number which is divisible by 11 is 110

    The last three digit natural numbers which is divisible by 11 is 990

    This is an arithmetic progression

    Where first term = a = 110

    Common difference = d = 11

    Let 990 be the nth term

    So

    a + (n-1)d = 990

    110 + (n-1)×11 = 990

    (n-1)×11 = 880

    (n-1) = 80

    n = 81

    So the number of Three digit natural numbers which are divisible by 11 is 81
