⇒ Number of campers in each team = 20 ÷ 5
⇒ Number of campers in each team = 4
Number of recorders in each team = 1
⇒ Number of searchers in each team = Number of campers in each team - Number of recorders in each team
⇒ Number of searchers in each team = 4 - 1
⇒ Number of searchers in each team = 3
Hence, there will be 3 searchers in each team
