We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
1. 1st line can divide a circular pie by maximum 2 pieces 2. 2nd line gives us maximum 4 pieces 3. 3rd line can cross 3 pieces (to cross 4 piece is impossible) and we obtain 1+3*2=7 pieces 4. 4th line can cross maximum 4 pieces and we obtain 3+4*2=11
It can be solve less than 1min by means of the consecutive steps

the key of this problem is the next line must be intersect all the previous line.so the answer is 2+2+3+4=11.Paint a chart is a directly and simply method. sorry ,my english is so poor and I can't clearly express my viewpoint.
If I see this in real gmat I'll never eat a cake again ...
hahahaha.. that's really funny. In my case, I'll be only focused on food after that point and not the quants. GMAT will be creaming me with such a question as my brain would immediately start thinking about food..

I personally don't like this question because it resembles too much of those brainteasers and I ended up with 14 pieces... 3 cuts would equal 7 pieces and then one linear straight slice horizontally would give me 14 pieces...
What is the maximum number of pieces that a circular pie can be divided into by four linear cuts?
A. 6 B. 8 C. 9 D. 10 E. 11
Can someone show this to me with a picture?
Such kind of combinations problems are always about a pattern recognition.
Maximum pieces: 0 line gives 1 whole piece; 1 line will gives 2 pieces: 1+1=2; 2 lines will give 4 pieces: 2+2=4; 3 lines will give 7 pieces: 4+3=7; 4 lines will give 7+4=11 pieces.
Similarly: 5 lines will give 11+5=16 pieces; 6 lines will give 16+6=22 pieces; 7 lines will give 22+7=29 pieces.
So, generally kth line will add k new pieces.
Answer: E.
P.S. Though I agree, it doesn't seem to be GMAT type of question.
