Are you sure that the ratios are correct? I'm not getting the OA... Or maybe I'm just wrong...
First, you have that j/(f+m) = 1/3, with f+m = 3j. So j+f+m = 1200 is the equivalent of j+3j = 4j = 1200, with j = 300. Suppose that f is the biggest it can be, meaning 1200 - 300 = 900 (with m = 0). This still is not consistent with f/(j+m) = 7/2, since 800/300 = 8/3 < 7/2....

Yep , something wrong . I am not getting answer as well. Did same thing what you did Danaj.

Danaj,

if j+3j = 4j = 1200, then j = 300...

but on solving further, i get M = -300/9
