12,24,32,44,52 are 5 possibilties ..

5 * 5 * 5 three digits and 5 for last two digits

625!!

Is this solution Helpfull? Yes (20) | No (4)  

PARAG KAMRA  (11 years ago)

the number divisible by 4 is only 4
so unit place can be filled in one way,and in other cases repetition is allowed ,so the combination will be
5*5*5*5*1=625 ans

ans is 500...
no. is divisible by 4 when last two digits are divisible by 4
_ _ _ 1 2 (5*5*5)= 125
_ _ _ 2 4 .
_ _ _ 3 2 .
_ _ _ 5 2 .
=125* 4 =500

just check the divisibility condition of in the last two digit of the 5-digit no. we will get (12,24,32,44,52) as combinations and rest as repetition is allowed 5*5*5*5=625

24 32 52 12 are divisible by 4 so digit in unit n ten place should b 24 or 32 or 52 or 12.. so ans is 5*5*5*4=500

Is this solution Helpfull? Yes (2) | No (2)  

PARAG KAMRA  (11 years ago)

the number is divisible by 4 is 24 and 42
so unit place can filled in 2 ways(either 2 or 4 can come)
tenth place can filled in 2 ways(either 2 or 4 can come)
and other three digit can be filled by 5 ways each,because repetiton is allowed
so the combination will be
5*5*5*2*2=500 ans

formula : 5^(N-1)
5^4

Sneha paliwal  (11 years ago)

ans =250.
There are two no .24 and 32 which is divided by 4 . means the possibility to place value at end two place is 2. and repitition of number allowed so that the total cases at first 3 place are
5*5*5 =125
now the total number is 125*2=250

Is this solution Helpfull? Yes (1) | No (6)  

Gourav Rusiya  (11 years ago)

5*5*5*5*2=1250
because at unit's place only 2&4 can come while at other places any of the 5 digits can come
