At a certain time in a park, the number of heads and the number of legs of monkeys and human visitors were counted, and it was found that there were 54 heads and 148 legs. Find the number of monkeys in the park.
Head = 54 Leg = 148 As we know – four legs of a monkey and two legs of a human visitor. Let total head have 4egs =54×4= 216 max leg = 216-148= 68 Men in park =68/2= 34 now monkey= 54-34= 20
