This question is related to Mixture and allegation, and the general formula for it is:
Net concentration = M*G + N*H/ M + N
Statement 1: Ratio of G to H is given, therefore G = 7k and H = 5k
Nothing is given for M and N so, it is not sufficient.
Statement 2: Ratio of M to N is given, therefore M = 3t and N = 4t
Nothing is given for G and H so, it is not sufficient.
1+2 ,
Now, putting both value in formula,
Net conc = 3t*7k + 4t*5k / 3t + 4t
= 21k + 20k / 7 = 41k/7
Still k is unknown, therefore both 1+2 is also not sufficient.
Therefore, option E is correct.

IMO E
We can't ge thte exact answer as we dont know the exact concentration. As both statement given are ratios.So both not sufficient individually as well as together

Gloss finish Percentage =x= (0.01GM+0.01HN)/(M+N)
AD ---> G:H given ---> x=0.01G{M+(H/G)N}/(M+N) --Insufficient
B ---> M:N Given ---> still G & H will be required to find %age. --> Insufficient
C---> upon combing both ---> x = 0.01 GM {1+(HN/GM)}/ M(1+N/M) ----> G required for complete solution Hence, answer is E.
