A blob regrows and does rampage. It doubles in size every hour. But after each hour it goes to sleep in the form of triangle. After few mins again gows. A satellite can cut thru blob whn asleep. U notice that the acute triangle ssection dies. But the triangle with obtuse or right angle wakes up. The blob sleeps in obtuse form. U can make 7 cuts. Cut can end on or in triangle
Every time u extend till other side a line, it makes acute angle on one side and obtuse on other, or right - right.
Inspiration frm pizza - when cut into 8,7,6,5 pieces, they form acute angled triangle.
So cut 2 lines in triangle to make it look like pentagon internally, after that cut even the pentagon into 5 pieces.
3 lions and 3 beast shd cross a river. Raft needs atleast 1 animal to paddle can carry two animals at a time. And needs atleast one line or beast in a row. If lions outnumber beast on either side, kill.
