Clearly statement 1 is insufficient.
from 2, 0.4< m/n <0.54.
Possible values are 5/11 and 4/9 and even 3/7.
Hence insufficient.
Combining both gives N=7.
from this the only possible value is 3/7.

I think answer is E, we may or may not get 3/7 from combining d statements, hence E,

(1) $$n = 7$$

(2) $$\frac{2}{5} < \frac{m}{n} < \frac{6}{11}$$

Here is my approach.
3/7=0.42 (approx.) --> Is $$m=0.42*n$$ ?

(1) $$n = 7$$ --> no info about m --> Not sufficient

(2) $$\frac{2}{5} < \frac{m}{n} < \frac{6}{11}$$ --> 0.4 < $$\frac{m}{n}$$ < 0.5 (approx.) --> $$0.4*n < m < 0.5*n$$--> Not sufficient

(1)+(2) Plugging $$n=7$$ into inequation: $$0.4*7<m<0.5*7$$ --> $$2.8<m<3.5$$ --> $$m=3$$ --> $$\frac{m}{n} = \frac{3}{7}$$ --> Sufficient
