there r x boxes in which a some dolls wree placed such that each box contains the same no of dolls and no dolls were left unpacked,if the no of boxes were reduced by 3 then the dolls packed and 5 dolls were left unpacked then find the total no of boxes ????

flowers_rsss

plss!! anyone

akshaybansal

i think the question is wrong

flowers_rsss

wat do u think is wrong in it ??can u expln pls!!!

akshaybansal

since 3 boxes are reduced and now 5 dolls are left unpacked

that means those 5 dolls were in those 3 boxes .

but according to question each box contains equal no. of dolls.

that means each box contained 5/3 dolls. that doesnot look practical

so i think there is something wrong with the question

flowers_rsss

no
actually after removing three boxes, dolls were repacked in the remaining boxes.

Hello flowers_rsss

Please check your query once again. akshaybansal' s doubt is right. Let's see it ---

Boxes = X and Dolls=Y

then in first attemp you put 'n' dolls in each box than

n.X = Y .........(1)

now in second attemp you have to put Y-5 dolls in X-3 Boxes so the equation becomes

n.(X-3) = Y- 5 ........ (2) using (1)

n.(X-3) = nX- 5

-3n = -5 or n= 5/3 which is ridiculous.

if you try to say that you have put m dolls in second attemp than the eqation becomes

m(X-3) = nX-5

or x = (3m-5)/m-n now are you able to get a unique or right solution from it...

Please see your query once again and post it correctly.

flowerssss there is something wrong with the question .

it has multiple (INFINITE) answers.

try the following

no. of boxes no. of dolls in each box

10 4

11 7

13 5

and so on .....

so i think some information in the question is incomplete

Hello akshaybansal

Your attemp is good but please check your (i) option once again.

Total dolls = 8 * 7 = 56 now reduce the boxes by 3 than boxes are 5 and hence 56/5 gives 11 dolls in each box and only one left.

But I am agree with you that question is incomplete.
