Question

A few students are recruited in order to find a few buried pieces of gold in a large area (assume it is a square). The large area is divided into a grid and each student is equipped with a gold detector which is able to detect if gold is present in the grid or not only if it is adjacent to the grid. If a student digs for gold on a grid point he/she also finds a number showing probability to find gold around that grid point. Each student can communicate with his/her nearest neighbour only(adjacent). Furthermore, upon detection of a piece of gold at least 2 students are needed to extract it from the ground. Other important details about the problem (feel free to assume relevant variables and have a good mathematical aptitude) (A). The number of students = 35 (B). Grid Size = 300x300 (C). The number of grids with gold = 25. Given the above constraints, you are supposed to think of a way in which the students can strategize their quest for gold in the least amount of time and effort possible​

Answer 1

Answer:

• A metal detector is an electronic instrument that detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground. They often consist of a handheld unit with a sensor probe which can be swept over the ground or other objects.
