Let C be a positive integer such that (c+7) is divisible by 5. the smallest integer n(>2) such that c+n^2 is divisible by 5 is

a)3 b)5 c)3 d)does not exist

Read Solution (Total 5)

In my opinion,

c + n^2 is divisible by 5 if and only if c and n^2 are both divisible by 5.
But, if c is divisible by 5 then c + 5 will not be divisible by 5.
So, option(d ) is correct.

C+7 divisible by 5, so the smallest possible c value is 3. n>2 so there exists no solution for (C+N)^2 divisible by 5

d cause as c+7 div by 5 lets take c as 3 then n>2 for c+n^2 div by 5 lets take n=3 so 3*3 is 9 +3=12 is not div by 5
