Out of 200 dog owners, is the number of owners who run their dogs greater than the number of owners who walk their dogs?
1. All of the dog owners who run their dogs also walk their dogs
2. 75 dog owners walk their dogs
S1) We know 0 owners run but do not walk their dogs. If 0 dog owners walk but do not run their dogs, then then #run = #walk. If >0 dog owners walk and do not run, then #run < #walk. We can definitively answer No. SUFFCIENT
S2) We know 75 walk and 125 do not walk. We don't know anything about number that run. INSUFFICIENT
Answer A
Hi I have a question here for S2.
So as you have rightly pointed out that 125 do not walk. So cant we take this as the number of dog owners that run their dogs? If not, please explain why? The only point that I can think of here is that there could some out of the 125 who neither walk nor run their dogs. But this has not been explicitly stated.
