the answer is A.

1: smallest range if 3 books with 200,200,200 and 2 books with x. 600 + 2x = 240*5 -> x = (1200-600)/2 = 300 -> range = 100 -> sufficient
2: insufficient (obviously)

the way i did this is as follows..wasnt sure..cuz the OA is C..??

what if, book1=$1, book2=$1

1+1+200+201+x=1200

202+201=403

x=1200-403=$797

range is 797-1=$796 > $80

if all 4 books have value = $200
200+200+200+200+x=1200

x=400

400-200=200..range >80

so A is sufficient..

I go the step by step :

Given: Median: 200 - Q: is range >80

St1: Avg= 240 (now why guys assumed 200 for 3 I dont know!!!) this is insufficient as it doesnt help us to find the range as tht could be < or >80 depending on the way u choose numbers

St2: 3 of them are 200 => {a, b, 200, 200, 200} or {200, 200, 200, a, b} is the set. we dont know anything abt a, b -----insuff

St1 +2: now we have a+b = 600 now the minimum value the range can take is when a=b=300

Hence C.

I go with it!!!!


EDIT: Guess wanted to prove the OA!!! :twisted:

I understand that A should be suffic.

A. To have 200.00 as a median price at least two other books should have a price less than 200 or equal to it. Since median is 200.00 and the average is 240.00, lets assume the followings:

Book 1 + Book 2 + median Book + x + x = 240 x 5
200 + 200 + 200 + x + x = 1200
600 + 2x = 1200
x = 300

so the range is > 80. so A.

B clearly is insufficient.
