A medical convention is attended by pediatricians and general surgeon only.
Given that: Number of pediatricians = 250, of which 40% is male .
pediatricians Male = 40%*(250) = 100.
pediatricians Female = 60% * (250) = 150.
Let the number of general surgeons = x
60% of x = Male Surgeons.
40% of x = Female Surgeons.
| Male | Women | Total | |
| paediatricians | 100 | 150 | 250 |
| General Surgeons | 60%x | 40% x | X |
| Total |
Statement 1:
(1) The ratio of male pediatricians to female general surgeons was 2 to 3.
100 / (40%x) = 2/3
solving it we get , x = 375.
Hence, Sufficient
Statement 2:
(2) There were exactly 150 female general surgeons in attendance.
40% of x = 150
x = 375.
Hence, Sufficient.
Both statements are individually sufficient.

Male Pediatricians : 0.4*250, Female : 0.6*250
Assuming pediatricians and general surgeons have no intersection, if total x number of GS, 0.6x male, 0.4x female. Now Statement 1 states that 0.6*250/0.4x ratio is something, can find x -- Hence sufficient.
Statement 2 directly gives 0.4x sufficient
