Re: Why USA will always need foreign workers with Math skills
the question should ask how much time it takes to cut the board into 4 pieces.... why 3 pieces? is there any logic?
leave it... seriously, no point scratching your head.

Re: Why USA will always need foreign workers with Math skills
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 ...

Re: Why USA will always need foreign workers with Math skills
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.

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
