-
- remainder will be(1!+2!+3!+4!)=33

- from 5! the sequence will have 0 in the units place,for which the remainder turn out to be 0.
the rest will be 1!+2!+3!+4!

- Clearly 5! onwards each is divisible by 5!.
SO the remainder will come from the division (1!+2!+3!+4!) divided by 5!
Now (1!+2!+3!+4!) = 1+2+6+24 = 33 and 5! = 120 so the remainder is 33. - 11 years agoHelpfull: Yes(11) No(0)
- after 5! the sum upto 50! is divisible by 5!=120 ,
but 1!+2!+3!+4! =33 is not divisible by 5!
so remainder is 33 - 11 years agoHelpfull: Yes(3) No(0)
- 1!+2!+3!+4!=33(rest numbers will be cancelles as it contains equals to or greater than 5!)
hence the remainder is 33

- 1+2+6+24=33
ans
- 11 years agoHelpfull: Yes(1) No(0)
- remainder will be 0
as we know sum of 1to 9 integers is equal to 55 which is divisible by 5 - 11 years agoHelpfull: Yes(0) No(8)
- 1!+2!+3!+4!=33
33%5!=33 - 11 years agoHelpfull: Yes(0) No(0)
