Question

Five digit number divisible by 3 is to be formed using the digits 0,1,2,3,4 and 5, without repetition. The total number of ways this can be done, is

Answer 1

the five digit number that is formed by 0,1,2,3,4,5 which is divisible by 3 is 54321

54321/3=18107

Answer 2

without 0 the five digit number are

5x4x3x2x1 =120

with 0 we don't use 3 then only the number divisible by 3

now we have 0,1,2,4,5

first we use 4 nonzero in 4 ways

second digit in 4 ways

so on

number of 5 digit number with 0 is 4x4x3x2x1=96

total 120+96 =216
