plz explain me the section marked in red above in your post... how did you assume that.. based on what information.. who said that the weights are ordered..??.. they can all be same or all be different by on 5 KGs..

all in J be 15.. but 44 in K be of diff wights.. then how do your propose to solve this question..??..

your explanation is hovering around one unwarranted assumption.. plz re-check and reply..

Hey varun,
I'm not assuming here. Ok.. let me put it in a different way..

Lets take boxes in shelf J.
If i start arranging according to their weights, the heaviest weight comes at the end. Now "Each of the 45 boxes on shelf J weighs less than each of the 44 boxes on shelf K". So all the boxes on K shelf come next. No assumptions here.

Now we need weight of 45 th box in order of arrangement.So 1) alone satisfies the condition.

Can you please elaborate on what my assumption are here?

ok.. 45 boxes each weighs 15KG in J

>>INFO NOT KNOWN TO US<<
but for 44 next boxes the weights are in ascending order starting from 20.. it wud be something like 20, 21, 22, 23....64 or lets say even worse example, 15.014, 16.123, 18.905 etc etc

now tell me wats the median?? Can u tell me the median value only on the basis of weight of boxes in J..??..

(1) The heaviest box on shelf J weighs 15 pounds.

(2) The lightest box on shelf K weighs 20 pounds.

my answer doesn't match with the OA.. and I am not sure if the OA could be true.. share your thoughts..

Here in the options the words heaviest and lightest are important. To calculate the median we need the weight of the 45 box. Now if we start arranging the boxes, we will first find all the boxes on J shelf followed by boxes on K shelf. Since we have the statement "Each of the 45 boxes on shelf J weighs less than each of the 44 boxes on shelf K". So the heaviest box on shelf J,which also happens to be the 45 box, is enough to answer the question. Hence A.

I hope i explained more clearly this time.

I'm loving the discussion on this thread.

Hey varun ...siddharth is absolutely correct ...there are no assumptions whatsoever ...

My attempt at explanation :
Median is the middle value of the set ...hence the median of 89 elements is the value corresponding to 45th element when arranged in a sequential manner ( ascending or descending, that does not matter ) ...

Now, it is pretty clear that each of the 45 boxes on shelf J weigh less than each of the 44 boxes on shelf K ...

Hence, sequence of 89 boxes would start from lightest box of shelf J to heaviest box on shelf K ...Hence middle value of the ordered set is the 45th box i.e the heaviest box of shelf J ....

Hence, St 1 is sufficient ...once we know the weight of heaviest box of shelf J, weight of all other boxes on shelf J become insignificant ..

It would not even matter if all of the boxes weigh equal or different ..

I hope this settles the doubt

Hey Varun,
Probably i'm not able to understand your question man. Anyways try to solve this problem after sometime.

Hello everyone,

How's it going? I am new to pagalguy.com and was wondering if you could help me out a little. I have attached a file (sorry for the inconvenience, but I needed the triangle from the question), whose solution I am unable to understand.

Can anyone help me out here??

[deepakraam]

I guess statement 1 alone is sufficient to ans the q

[akhanna]

You got the answer right!! But how do I solve it?? Its just not coming to me. I believe it has something to do with similar triangles, but I just can't seem to derive it.

Any further help would be greatly appreciated!!

[akhanna]

By the way, thanks for the prompt reply, deepakraam !! Hope to hear from you soon on how to solve this problem for "Statement 1 alone is sufficient".
