Question

How many 5 digits number can be formed using 1,2,3,4 & 5 such that
a) Is divisible by 2
b) is divisible by 3
c) is divisible by 4
d) is divisible by 5​

Answer 1

Answer:

there are not any number which can be formed using the digits 1,2,3,4,5 because

the number which is divisible by 2 always ends with 2,4,6,8 and 0

and the number which is divisible by 5 always ends with 5 and 0

here , the number will be formed if it will be divisible by 5 then it can't be the factor of 2
