Question
How many three digit numbers are divisible by
5?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
564.932 + 849.029 – 425.08 = 612.095 + ?
999.99 + 99.99 + 99= ?
