How many five digit numbers can be formed using the digits 2,3,8,7,5 exactly once such that the number is divisible by 125?

a. 0

b. 1

c. 4

d. 3

As we know for a number to be divisible by 125, its last three digits should be divisible by 125

So for a five digit number, with digits 2,3,8,7,5 its last three digits should be 875 and 375

Hence only 4 numbers are possible with its three digits as 875 and 375

i.e. 23875, 32875, 28375, 82375...**Write Here**
