There are 504 different 3-digit numbers which can be formed from numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 if no repetition is allowed.
How many three digit number can be formed from digit 1 to 9 such that digits are in ascending order a 84 B 144 C 81 D 72?Therefore 84 numbers can be formed.
How many three digit numbers can be generated such that digits are in ascending order?numbers starting from 1 is given by the sum of 1 to 7 = 28. Thus a total of: 28 + 21 + 15 + 10 + 6 + 3 + 1 = 84 such numbers.
How many 3Hence, 999 is the 900th term of the sequence i.e. there are 900 three digit numbers.
