Question

A long Wire has to be cut into 23 small pieces if it is double foulded to start with how many times does it used to be cut ?​

Answer 1

Step-by-step explanation:

If it's folded once to get a "U" shape, and you cut near the ends of the ropes, you get two little pieces plus one long piece. So cutting once like this gives you 2+1=3 pieces, cutting twice gives you 2+2+1=5 pieces, cutting three times gives you 2+2+2+1=7 pieces
