A is correct
1) June plus May = 40,000
J+14,000 = 2M
J+M = 40,000
M = 18000 J = 25000, So J>M -- Sufficient
2) J > 12,000
assume J = 12001 M = 13000.5 So J<M
But if J = 50,000 M = 32,000 So J> M

感谢回复~~
可是
题中条件是【 if JUNE的收入 more than 14000,那么JUNE的收入就是MAY的2倍。】→ 当June>14000,有June=2May
1)J+M=40000。
要是June<14000,June=2May这个条件就无法用了啊。。比如june10000,may30000也可能
还是我理解错了。。。。
