Question

# Explained answer @ Linear Equation in two variables. In a deer park there are some deer and some humans. If the number of head here is 53. The number of legs is 160. Find the number of deer and the number of human​

Answer 1

Answer:

no of dear is 53 and human is 40

Answer 2

Let x be the total no of legs of deer

let y be the total no of legs of visitors.

∴x + y = 132

∵1deer has 4 legs and 1 head & 1 visitor has 2 legs and 1 head

∴x/4 + y/2 = 39

plotting the graph we get the point of intersection which is the value of x and y.

thus from the graph we can say x = 108 and y=24

∴ num of deers = 108/4 = 27

∴ num of visitors = 24/2 = 12
