(1) John picked 15 rings from the bag.
(2) John picked 3 gold rings
Straightforward question, so let's dive into the statements. As always, let's start with the simpler one.
(2) fits the bill - no information about either silver or bronze rings chosen, so clear insufficient: eliminate B and D.
(1) Let's pick numbers to see if we can get both a "yes" and a "no" answer.
John could have picked 7 silver and 8 bronze. Is 8 more than 7? YES
John could have picked 7 silver, 5 bronze and 3 gold. Is 5 more than 7? NO
YES and a NO - insufficient, eliminate A.
Since neither statement was sufficient alone, we now combine them into one long statement:
John picked 15 rings, 3 of which were gold.
Or:
John picked a total of 12 silver and bronze rings.
Picking numbers:
John could have picked 8 bronze and 4 silver. Is 8 more than 4? YES
John could have picked 5 bronze and 7 silver. Is 5 more than 7? NO
Still a YES and a NO: insufficient, choose E.
