Question: Boy's who didn't pass = ?
Statement 1: 321 girls didn't pass the test, which is the number of boys that did.
Total = 990
Girls didn't pass = 321
Boys passed = 321
Girls Passes + Boys failed = 990-(321+321)
NOT SUFFICIENT
Statement 2: Boy's didn't pass = (1/5)*totalTotal = 990
Boys didn't pass = (1/5)*990 =198
SUFFICIENT
Answer: Option B

T = 990
BnP =?
T = BP + BnP + GP + GnP (Boy's passed + Boys not passed + Girls passed + Girls not passed)
Statment 1
GnP = 321 = BP
990 = 321 + BnP + GP + 321
This gives GP+BnP but no information on the composition
Insufficient
Statement 2
BnP = 990* 1/5
Sufficient
BnP =?
T = BP + BnP + GP + GnP (Boy's passed + Boys not passed + Girls passed + Girls not passed)
Statment 1
GnP = 321 = BP
990 = 321 + BnP + GP + 321
This gives GP+BnP but no information on the composition
Insufficient
Statement 2
BnP = 990* 1/5
