this is easy C.

from i get the ratios and from ii get the number of men.

w/c= 5/2

c/m = 5/11

w/m= 25/11
w = 25
m = 11

ST1. W:C is 5:2, C:M is 5:11

=> W:M is 25:22 (multiply 1st ratio by 5 and 2nd ratio by 2 so that C=10)

Not sufficient, because there infinite number of case that satisfy this ratio

ST2. W<30. This statement alone doesnot give us any info about Men.

ST1 & ST2: W:M is 25:22 AND W<30. The only possible way for this to be true (without cutting women into pieces :)) is if number of women = 25. Then Men=22.

So, together SUFF.

(C)

Given w:c = 5:2

S1: c:m = 5:11
Therefore, w:m = 25:22
Not sufficient.

S2: #w < 30 Not sufficient.

S1 & S2: w/m = 25/22

Therefore, m = 22
Sufficient.

Answer: C

1 is insuff, since it gives the ratio of M:W:C. However it does tell us that since fractions of humans cannot exist. min. women =25

2. insuff by itself, M is missing from ratios

combining 1, 2 we know that w=25, so can find M and so answer is C

C

Given
W/C = 5/2

1) C/M = 5/11 Not suff

2) W<30 Not suff

Together
Remember C M and W have to be integers
henc W can be 25, 20, 15, 10 or 5

When W = 25 , C = 10 and M = 22
when W = 20 , C = 8 but M is nto an integer

Same thing when W = 15,10 or 5
Hence only with W = 25 we get the number of men

(2) no mention about Men

ACE

(1) Insuff

(1) & (2) only Women =25 would give an integer value for Men

Hence Suff

C
