What do you see in the given picture?
Four people need to cross a rickety bridge at night. Unfortunately, they have only one torch and the bridge is too dangerous to cross without one. The bridge is only strong enough to support two people at a time. Not all people take the same time to cross the bridge. Times for each person: 1 min, 2 mins, 7 mins and 10 mins. What is the shortest time needed for all four of them to cross the bridge?
By including only four matchsticks in below picture, you have to make "Four Triangles And Two Squares"
Can you move 2 matchsticks to form four equal sized squares.
