Good question

statement 1 : m/n = 12.64 ,

we know m & n both are integers , therefore 12.64 * n = m (integer value)
if we convert 12.64 into fraction we get = 1264/100 = 316/25
so n can be any multiple of 25,
n= 25,50,75, 100.......
therefore m = 316 , 632, 948 , 1264.....
remainder = 16 , 32 , 48....... ---> Insufficient

Statement 2 : n<50
we cannot determine value of m ----> Insufficient


statement 1 & 2 together , we get n=25 and m= 316 ----> Sufficient

answer is C
