Cha, the answer is 20. There is a big long board (as shown in the figure). If you cut it at any point with a saw, it is going to produce two pieces of boards, which is going to take 10 minutes ... So if you want to make another cut, regardless of how many pieces you get, it is going to be 10 extra minutes ... I dont see how it could be 15 minutes ...

marie board pe saw chalaayegi...uske 2 piece hongay...uske baad marie ko paseena aayegaa.....marie nahaane jaayegi...

marie jabb nahaa rahi hogi to usko dhyaan aayegaa ke thodi waxing/shaving ki bhi zaroorat hai...to woh apni denting painting karegi...

phir makeup karegi...kapde choose karegi...kisi mein bum bada lagegaa...kisi mein bust chhoti lagegii.....

uske baad bhookh bhi lagegi bechari thaki hui marie ko...phir rasoi mein jaa ke aloo gobi banaayegi...

khaane ke baad dil karegaa coffee ka to starbucks se ek coffee laane jaana padegaa...gaadi ko reverse mein driveway se niklaane mein 15 baar gaadi ke gear badalne padeingay..

Thank you for staying on topic and giving the right answer. Yes, it takes 10 minutes to cut a board into two pieces. So no matter what, it will always take 10 minutes to cut the board. So the right answer is 20 minutes.

Mr. Shringarey bitterly cribbed to a Mr Uptil, a field man. Mr. Uptil went to a a local school. He pointed the error to the headmistress. His tone was chiding.

The headmistress turned back to Mr Uptil and shouted "First you jokers decide - decide once and for all what 23 x 19 is - and then talk! You people are confusing the studends!!"

Cool! This one is a modern version of shiva dhanushya episode which Ram broke in Sita swayamvar. A school inspector visits the school:

Inspector: Who broke Shiva dhanushya?

Student: I didn't; I wasn't even here in the school until now.

Teacher: Yes, he did not; he sits on his dads bidi shop in the mornings and just came.

Principal: Well, whatever it is, the school will pay the damages and let's be done with it and head for chai pani.

Big Deal.

There are 4 stages of work

1. Thinking about getting the work done
2. Thinking about how to get the work done
3. Actually doing the work
4. Recognizing that work was done

The USA excels in 1 & 4.
India excels in 2 & 3.

The right answer is 15 minutes. The implicit assumption being that the board is of a particular shape and will be cut in a certain way.

Take a piece of square board. Cut along lengthwise (or width wise, it does not matter in the first cut). The time it takes is 10 minutes (as stated).

Now, take one of the two pieces so generated, and cut it along its shortest dimension. Because the shortest dimension is one half the other dimension, the time taken is one half as well. Thus the time required is 5 minutes.

The total time is 10 + 5 = 15 minutes. The pieces generated are 3, one big and two small pieces.

Obviously, I think otherwise

My daughter gave me the same answer dhurru pai. Kya correct socha hain.

You are just adding a lot of conditions and assumptions which were not present in the present problem. Offcourse since you have to always show your 'otherwise' thinking, it is excused and I would believe any answer you came up with. Even 12 minutes!
