How many 9 digit numbers which are divisible by 4 can be formed by using the digits 1 to 5 if repetition of digits is allowed?
Reqd no. is 9 -digits.. available digits are 1 2 3 4 5.. Numbers which are divisible by 4 can be determined by the last two digits.. from the given combinations,, the numbers div by 4 are 12, 24, 32, 44, 52
so.. the number's last two digits can be any of the above 5.
Hence, we have to calculate the combinations for the first 7 digits..
Ans: (5C1)^7 * 5
ie 5^8 = 390625
