n!-(n-1)! is the answer. n is number of digits here. (n-1)! is subtracted from n! since there is digit with 0. otherwise it is just n! Now How do you calculate n!. For example 4! here. 4! = 4x3x2x1 = 24 (4-1)! = 3! = 3x2x1 = 6 Hence the answer is n! - (n-1)! = 4! - (4-1)! = 4! - 3! = 24 -6 = 18 Option D is the answer.
