IMO A

1) when n+45/n,rem= 12....so,n can be 45-12 = 33....here it cannot be 11 since rem is always < the divisor...hence 33

2) n is odd, insuff

then f(n + 45) will be 45 and not 12.

57+45/57,rem = 45

Stmt I

n+45 / n = Q + 12 where Q is the quotient

n+45 = nq+12

n(q-1) = 33

n has to be less than 15

SUFF

Stmt II

n is odd

n=7,17... etc many possible values

I agree with A

Hi, I think you have to check the bold statement above.

n(q-1) = 33.

Also since the remainder in 12, n must be greater than 12.

hence the only value for n is 33.

So n>15.
