Number of people:
Only A = a
Only B = b
Both A and B = c
Neither A or B = d
=> a + b + c + d = 580
To find: a
St. 1:
a + b = 226
Cannot determine 'a' from this
=> St. 1 is insufficient.
St. 2:
d = 187
b + c = 281
=> a + b + c + d = 580
=> a + 281 + 187 = 580
=> a = 112
=> St. 2 is sufficient.
Answer: B
Only A = a
Only B = b
Both A and B = c
Neither A or B = d
=> a + b + c + d = 580
To find: a
St. 1:
a + b = 226
Cannot determine 'a' from this
=> St. 1 is insufficient.
St. 2:
d = 187
b + c = 281
=> a + b + c + d = 580
=> a + 281 + 187 = 580
=> a = 112
=> St. 2 is sufficient.
Answer: B
