Brain teasers and challenges.

Now tell how much it costs(damages) for the original shopkeeper.

I guess it's Rs.1k profit to him? or Rs.800 loss?
I can't get the question. It is not lucid and understandable.

Now see and answer should come with a strong explanation. It should be comfortable. I also don't know it. Still trying, still struggling.
 
I'll pass because the question is not clear(or I'm not understanding it, whatever)

Why is it better to have round manhole covers than square ones?

Explain.

Which manhole you talking about? Drainage cover or one that I'm thinking of.:p

I guess its due to square shape it can't be placed perfectly with change in dimension. It may fall inside. That doesn't happen with circular one. Maybe?

to be more clear if you keep the square diagonal it will fall inside, circular wont

A woman bought some items from a grocery shop worthing 200 rupee. Shopkeeper sold items of 200 rupee to that lady.

The lady given an 1K rupees note to the shopkeeper. Shopkeeper hadn't the change of 1K rupee so he took 1K as loan from neighbor's shop, kept 200 rupee himself and returned 800 rupee to the lady.

Later sometime the second shopkeeper came with that 1K note and returned it. Plus he shown that its fake and took back his 1K rupee from grocery shopkeeper and went.

Rs 1200 (if we do not consider any profit in the goods worth Rs 200). He has a fake note of Rs 1000, so that's a straight loss, and he's given away goods worth rs 200, so that's a loss.
1000+200=1200

Now tell how much it costs(damages) for the original shopkeeper.

The loss will be 1000 I think. Here is my explanation:

Particulars|Amount/Cost
Cost of Goods Sold|200
Add: Money returned to customer|800
Total|1000

Now, coming to the transaction between the two shopkeepers, Our shopkeeper say 'A' got the change from the other shopkeeper say 'B' and gave Rs.800 to the customer. He now has Rs.200 with him. Later, B comes to A and demands money so A takes back the fake note and gives him Rs.800+200 (balance left with him after giving Rs.800 to the customer). Here, his loss is Rs.800 that he already paid to the customer. How? Because in exchange of Rs.800+200, he did get the change of Rs.1000 from B early on so that amounts to 800+200 in exchange of the change of Rs.1000. So the difference here is Rs.0. Now, coming back to the original transaction.

Particulars|Amount/Cost
Cost of Goods Sold|200
Add: Money returned to customer|800
Add: Loss for A from the transaction with B|0
Total|1000

Hence, the total loss to be borne by the shopkeeper A will be Rs.800 and goods worth Rs.200 amounting to Rs.1000 in cash and kind.

I think it is the hypotenuse that is creating an illusion here because it is not a straight line.

There is no icon for table in the options. You have to type the tags to form a table. Please quote my message to check how it is done.

It's not an illusion, if you print it out, cut the pieces and rearrange, you'll see the same dilemma.

Yes okay but isn't it happening because of the hypotenuse? What is your answer?
 
I took the photo into photoshop and I feel there is a slight difference in the thickness of the borders and the size of the shapes. Looks like an illusion to me.

Besides, if you look at the "graph", some lines are thick, and some are thin, if we consider the number of thick and thin lines in a shape, we might get to something.
