    How many three digit numbers are divisible by

    5?
    A 160 Correct Answer Incorrect Answer
    B 170 Correct Answer Incorrect Answer
    C 190 Correct Answer Incorrect Answer
    D 180 Correct Answer Incorrect Answer

    Solution

    nth = a + (n – 1)d Here, a → first term, n → Total number, d → common difference, n → n term Common difference, (d) = 5 Now, n = a + (n – 1)d ⇒ 995 = 100 + (n – 1) × 5 ⇒ 995 – 100 = (n – 1) × 5 ⇒ 895 = (n – 1) × 5 ⇒ 179 = (n – 1) ⇒ n = 180
