Of the 800 sweaters in a certain store, 150 are red. How many of the red sweaters at the store are made of pure wool?
1) 320 of the sweaters at the store are neither red nor made of pool wool
2) 100 of the sweaters at the store are not made of pure wool
1) no information to come with pure wool red sweaters
2) 150-100= red pure wool sweaters
Ans. B.
What is the correct answer? please help.
I believe there is a problem in this question:
1) 320 of the sweaters at the store are neither red nor made of pool wool
This means that there are at least 320 NOT PURE WOOL sweaters.
2) 100 of the sweaters at the store are not made of pure wool
This tells are that AT MOST 100 sweaters at the store are NOT PURE WOOL sweaters.
Two contradicting statements.
I may be wrong.
