if 1( 1! +2! + 3!+.....50!) id divided by 5 what is remainder?

• (1+2+3*2+4*3*2)+(5!+6!+.....50!)
  2nd part s completly divisible
  and sum of 1st part is 33 after divided by 5 we get 3 remainder

• 1!=1,2!=2,3!=6,4!=24,5!=120....and so on
  factorial of more thn or equal to 5 is a multiple of 5.
  so by addition,we get
  1+2+6+24+5(24+...)
  =33+5(x)
  =3+5(6)+5(x)
  =3+5(6+x)
  so ans is 3
