2) Which of the following is true

3) For a natural number n, which one is the correct statement

4) Let P(x) be a polynomial , which when divided by x-3 and x-5 leaves remainder 10 and 6 respectively . If the polynomial is divided by (x-3)(x-5) then the remainder is

5) If x and y are digits such as 17 ! 3556xy4280960000,then x+y equals

6) The remainder obtain we 1!+2!+3!+=....11! is divided by 12 is
